ABA Type Triblock Copolymer Based on Mesogen-Jacketed Liquid Crystalline Polymer: Design,Synthesis, and Potential as Thermoplastic Elastomer
We have designed and successfully prepared a well-defined ABA type triblock copolymer consisting of poly(n-butyl acrylate) as soft B block and poly{2,5-bis[(4-methoxyphenyl)oxycarbonyl]styrene} (PMPCS) as hard A block with potential as liquid crystalline thermoplastic elastomer (LCTPE). The synthetic strategy is to obtain a difunctional poly(n-butyl acrylate) first and then use it as a macroinitia...

Photoinduced Holographic Phase Gratings Buried in Azobenzene Side-Chain Polymer Films with A Chiral Group
An optically active polymer(PM1) containg zaobenzene moieties with a chiral group (s-2-methyl-butyl) was synthesized by homopolymerization of monomer,4-[2-(methacryloyloxy)ethyloxy]-4`-(s-2-methyl-1-butyloxycarbonyl) azobenzene,using the free radical polmerization method. The polymer dissolved in tetrahydrofuran(THF) could be easily proessed into high optical quality films. The optical anisotropy ...

Effect of Steady Shear on the Morphological Evolution of Biodegradable PLA/PCL Blend. Polymer Engineering & Science, 2009, 49(12), 2293 - 2300.
Polymer Engineering & Science, 2009, 49(12), 2293 - 2300.
ABSTRACT:
The biodegradable polymer blend containing 70/30 weight ratio of polycaprolactone (PCL) and polylactide (PLA) was prepared via melt mixing. The evolution of the ‘sea-island’ phase structure in the steady shear flow was studied using scanning electron microscope (SEM) and parallel-plate rheometer. The r...

Study on Physical Properties of Multi-Walled Carbon Nanotube/PPS Composites. Polymer Engineering & Science, 2009, 49(9), 1727-1735.
Polymer Engineering & Science, 2009, 49(9), 1727-1735.
ABSTRACT:
The multi-walled carbon nanotubes were directly compounded with poly(phenylene sulfide) (PPS) via melt mixing. The morphology and physical properties, including viscoelasticity, electrical conductivity, thermal and mechanical properties of the obtained composites were investigated. The results show that the purified nanotubes ...

Nano-Structural Evolution Induced Degradation of Polylactide/Clay Nanocomposites during Isothermal Cold Crystallization. Polymer International, 2009, 58(3), 430-436.
Polymer International, 2009, 58(3), 430-436.
ABSTRACT:
BACKGROUND: The aim of the work presented was to study the nano-structural evolution of the clay tactoids during the isothermal cold crystallization of the polylactide/clay nanocomposites (PLACNs). An interesting degradation behavior of the matrix PLA, however, was observed simultaneously with nano-structural evolution. Thus the possib...

Linear Viscoelastic Properties and Crystallization Behavior of Multi-Walled Carbon Nanotube/PP Composites. Journal of Applied Polymer Science, 2008, 108, 1506-1513.
Journal of Applied Polymer Science, 2008, 108, 1506-1513.
ABSTRACT:
Multi-walled carbon nanotube/polypropylene composites (PPCNs) were prepared by melt compounding. The linear viscoelastic properties, nonisothermal crystallization behavior and kinetics of PPCNs were respectively investigated by the parallel plate rheometer, differential scanning calorimeter (DSC), X-ray diffractometer (XRD) and...

Phase Behavior and Its Viscoelastic Responses of PLA/PCL Blend. European Polymer Journal, 2008, 44, 2171-2183.
European Polymer Journal, 2008, 44, 2171-2183.
ABSTRACT:
Polylactide (PLA)/polycaprolactone (PCL) blends with various blend ratios were prepared via melt mixing. The morphology, linear and non-linear viscoelastic properties of the blend were studied using scanning electron microscope (SEM) and cone-plate rheometer. Three typical immiscible morphologies, i.e., spherical droplet, fibrous and co-c...
