Speech Title: Ethylene Polymerization in the Nano-channels of Mesoporous Molecular Sieves
Abstract:Ethylene polymerization plays significant roles in modern society. Mesoporous molecular sieves (MMS) act as both the catalyst support and nanoreactor for ethylene polymerization. MMS, typically MCM-41 and SBA-15, offers suitable pore sizes for ethylene polymerizations to proceed in an extrusion mode in which the formation of polymeric nano-fibers composed of extended polymer chains from the nanopores of MMS is completed in one step. Moreover, the polyethylenes (PE) and ethylene copolymers (ECP) are in situ compounded with MMS particles to form polymer nanocomposites when the MMS framework collapses due to polymeric chain growth and/or enormous polymerization exotherms. Such a facile methodology integrates numerous merits into one and endows the resultant ethylene (co)polymers with significant advantages, such as increased molecular weights and their distribution, elevated strength and modulus, and improved processability, and so on. This talk addresses the progress in ethylene (co)polymerization catalyzed by organometallic complexes (pre-catalysts) immobilized onto various molecular sieves and property investigation on the resultant polymers over the past 10 years. This talk comprises three main parts focusing on pre-catalysts immobilization, ethylene polymerization in MMS, and the structure and properties of the as-fabricated products from ethylene polymerization.

Speech Title: Solvent-Induced Crack Growth and Healing in Polymers
Abstract:Solvent transport in polymer accompanied with chemical stress has been studied by many researchers. During absorption, the stresses are compressive near free surface of polymer and tensile in the center. These stresses can be relaxed by swelling, cracking or crystallization. If crack exists, crack healing is possible to happen. Crack healing is classified as thermal, solvent and adhesive healing. Solvent healing is followed the process of sorption and desorption. Sorption behavior in polymer has been studied widely. However, solvent desorption in polymer is an intrigue issue. In this paper, the effect of desorption rate on fracture behavior in polymer was investigated. Two solvents of methanol and 2-ethylhexyl alcohol were used for sorption and desorption studies, respectively. 2-ethylhexyl alcohol accelerated methanol extraction from polymers so that crack initiation and growth was observed. The crack initiation and growth arise from the tensile stresses induced by methanol desorption. Crack density was observed by optical microscope and calculated by software Image J. Crack density and depth depend on immersion temperature and period. Fracture strength was measured using a universal tensile teat machine. Note that when polymer is immersed in methanol and then exposed to air, no crack initiation is found. The healing rate increases with increasing solvent temperature. The location of crack healing was identified by dye which was mixed with methanol to diffuse in polymer

Speech Title: Biomimetic Adhesion and Its Applications for Developing Functional Polymeric Materials
Abstract: Biomimetic adhesion is an emerging scientific field, which learns engineering principles and acquires scientific insights from superior biological designs and applies them to develop novel adhesive and coating materials. In this talk, our research on the adhesion of surfaces and thin films inspired by such biological systems as the lotus leaves’ anti-adhesive and self-cleaning surface, the lizard gecko’s dry adhesive “hairy” toe pads, and the marine mussels’ superior wet adhesive systems will be first reviewed. The systematic studies of mussel-inspired polydopamine thin film and its application for the functionalization of polypyrrole will be discussed in detail. Polypyrrole is an interesting type of electrically conductive polymers but is difficult for large-scale processes because of its hydrophobic chemistry. We developed an innovative way to fabricate polypyrrole nanostructures by incorporating the mussel-inspired catechols (e.g. dopamine) in the oxidation polymerization. The dopamine-functionalized polypyrrole has tunable nanostructures (e.g. nanofibers, nanoflakes, nanorods) that can readily be dispersed in aqueous solutions and form thin coating film with good surface adhesion and enhanced electrically conductivity. In addition, such interfacial phenomena as wetting, adhesion, friction, dispersion and associated micromechanical properties or processes will be highlighted and discussed in terms of their technical implications for the development of functional polymeric materials.

Speech Title: Impact Strength Prediction for Notched Engineering Polymers
Abstract: Engineering Polymers such as polycarbonate have been used for mobile phones and exterior equipment of automobiles because of their superior impact resistance. In this study, the impact properties of polycarbonate were considered in terms of the time-temperature superposition principle. The dynamic strain rate at the notch root for high speed tensile test was analyzed as a major factor to control viscoelastic property. Then, the master curve for the final fracture elongation was expressed in terms of the strain rate at the notch in conjunction with shift factors. From the maser curve the fracture behavior can be predicted for the wide ranges of impact speed and temperature. The usefulness of the elastic analysis was also confirmed by comparing with the elastic-plastic results.

Speech Title: New strategies for enhancing capacitive deionization capability of functional carbon materials
Abstract: The sustainable supply of fresh water has been one of the key issues for the whole world, which will remain forever as long as we human beings live on the earth. To tackle this issue, novel yet high performance water purification technologies are highly demanded, for example, the production of fresh water from sea or brackish water. The capacitive deionization (CDI) technology, a kind of flow-through supercapacitor, has been regarded as a robust, energy-efficient, and cost-effective alternative for desalination of sea water or brackish water, which has drawn much attention in the past decade. The CDI process is based on the adsorption and desorption of ions onto the carbon electrodes via an electrical double layer (EDL) scheme, of which one of the key and bottle-neck issues is the design and fabrication of functional carbon electrodes with tuned structure and properties. This talk will present our recent achievements made in the synthesis of carbon materials for CDI with an focus on the optimizing the structure-property-desalination performance.

Speech Title: Surfactant-functionalization of polyethylene and polypropylene hydrophobic polymeric supports for adsorption of anti-oxidant polyphenols
Abstract: Polythylene (PE) and polypropylene (PP) are examples of low density nonionic polymers. The binding of the surfactant and solvent phase to the nonionic polymers is by hydrophobic adsorption. A minimum hydrophobicity is essential for the polymers to be used. The nonionic and non-functional polymers were functionalized employing a surfactant and were characterized using, FTIR, SEM and BET techniques for adsorption of polyphenols. The pore distribution of functionalized materials falls between macroporous and mesoporous domains. Their specific surface areas are typically in the range SBET = 20-35 m2/g. The adsorption capacities of the functionalized polymers were found to be comparable to those of customary adsorbents. Geometrical optimization was performed at the density functional theory (DFT) level to gain insight into the mode of interaction between supports and polyphenols. This talk will highlight three main parts focusing on pre-surfactant functionalization of PE/PP supports, characterization and mechanism of poyphenol adsorption onto them

Speech Title: Prediction of load-deflectionbehavior of multi-span FRP and steel reinforced concrete beams
Abstract: In this talk a numerical procedure to determine the deflection of concrete members reinforced with fiber reinforced polymer (FRP) or steel bars will be presented. This procedure is implemented into the stiffness matrix to allow for general use in the structural analysis. It considers effective flexibilities of members in the cracked state using either the curvature distribution along the member or available effective stiffness models under any loading or support conditions. In general, structural concrete members can be considered to have three cracked regions (two at the ends and one at midspan) and two uncracked regions along their length. In this numerical procedure, the contributions of these regions to the member stiffness matrix are computed using a numerical integration technique. Using this procedure, a software program is developed which allows for the load-deflection behavior of a member reinforced with either FRP or steel bars and subjected to any loading or support condition to be rapidly determined. This calculation procedure is evaluated using available experimental data on the load-deflection behavior of simple and two-span beams reinforced with FRP and steel bars. Through comparison of the results, it is observed that the load-deflection behaviors calculated using the proposed approach utilizing the member moment-curvature response are consistent with the experimental data. This approach can provide a useful tool for the general calculation of deflection regardless of reinforcement type and can be used throughout entire range of member behavior up to flexural failure.

Speech Title: Crystallization Induced Phase Separation and Lamellar Re-Orientation for Optical Birefringence Reversion in Polymer Spherulites
Abstract: Atomic-force and scanning electron microscopies (AFM, SEM), wide-angle and small-angle X-ray diffraction (WAXD and SAXS), and thermal and infrared spectroscopy characterization, were used for probing the mechanisms and correlations between lamellar re-assembly, phase separation domains, and birefringence patterns in crystallized spherulites in poly(hydroxyl butyrate) (PHB) were probed in details. Crystallization-induced phase separation in PHB blended with amorphous poly(methyl acrylate) (PMA) produces pebble-like PMA domains, which influence the birefringence types (positive vs. negative types) of spherulites in crystallized blends with respect to composition and temperature. Extents of crystallization-induced phase separation were dependent on temperature and composition; for a fixed PHB/PMA (60/40) blend composition the phase separation extent was inversely proportional to temperature of crystallization (Tc). Correspondingly, depending on the extents of phase separation (counted as quantitative ratio of pebble-like PMA domains divided by entire area of the blend samples), the Maltese-cross in spherulite patterns of PHB in the blend may rotate from the original positive-type spherulites at Tc = 90oC to negative-type spherulites at Tc = 60oC. The SAXS analyses showed the lamellar thickness variation of PHB lamellae (or PHB+amorphous polymer long periods) with Tc was not an influencing factor, but that the formation of grains in the PMA domains from the crystallization-induced phase separation could majorly influence the optical birefringence.

Speech Title: Tension Stiffening Effect on the Flexural Behavior of FRP and Steel Reinforced Concrete Beams
Abstract:In this talk, tension stiffening effect on load-deflection behavior of concrete beams reinforced with FRP and steel bars is presented. In order to investigate tension stiffening effect on flexural behavior, bilinear tensile stress-strain model was considered for concrete material. In this modela parameter controls the tension stiffening effect on the load-deflection behavior of the beam. Load-deflection curves of 12 FRP reinforced concrete beam specimens available in the literature were obtained with varying this parameter between 2 to 25, and then were compared with the experimental results. In conclusion it is observed that the value of tension stiffening parameter to be taken into account for calculations in order to predict load-deflection behavior of reinforced concrete beams significantly depend on the reinforcement ratio and the mechanical properties of reinforcement.

Speech Title: Synthesis of PVDF Based Ferroelectric Polymers with Tunable Ferroelectric Performances
Abstract:Poly(vinylidene fluoride) (PVDF) based relaxor ferroelectric polymers show great potential application in transbucers, sensors and artificial muscles for their excellent electrostrictive properties. In state-of-the-art relaxors, trifluoroethylene (TrFE) units have to be incorporated to maintain the TTTT conformation of PVDF polymer chain, which is crucial to achieve large polarization under electric field. To accelerate the polarization relaxation of ferroelectric domains, defects have to be designed to tailor the sequence length of PVDF chain in TTTT conformation by either exposing the P(VDF-TrFE) films to electron beams or inserting bulky comonomers into the polymer chains.More...
