Cellulose Nanowhisker Reinforced Poly ( vinyl alcohol) /Pectin Composite Films
关键字：Cellulose, Nanowhisker, Poly(vinyl alcohol) , Pectin, Film
Cellulose nanowhiskers (CNWs) with an aspect ratio of over 10 were prepared from ramie by acid hydrolysis. CNWs were added to poly(vinyl alcohol) (PVA), pectin and their blends to prepare films through casting m...

VISCOELASTICITY OF CROSSLINKED POLY(ETHYLENE-CO-PROPYLENE) COMPOSITES
关键字：VISCOELASTICITY,CROSSLINKED,POLY,ETHYLENE,PROPYLENE,COMPOSITES,
Elastomers exhibit an instantaneous, reversible strain when subjected to a stress. Real elastomers show some unrecovered strain or creep since all molecules must not be included in the network structure. If crosslinking is increased&nb...

Crystallization behavior of modified poly(ethylene terephthalate) with varied macromolecular architecture
关键字：Crystallization behavior, modified poly(ethylene terephthalate), macromolecular architecture
Several modified poly(ethylene terephthalate) were prepared. The crystallization behavior of them was studied by DSC and POM. It was found that small extent of branching may enhance the crystallization, while high degree of branching&n...

Temperature-controlled responsive Poly(vinylidene fluoride)PVDF membranes by grafting poly(N-isopro -pylacrylamide) on them
1. Introduction
Poly(vinylidene fluoride) (PVDF), owning good heat, corrosion and solvent resistance[l], be
prepared into flat sheet membranes and hollow fiber membranes [2], which are widely applied to
various fields such as water purification, organic solvent refining and membrane distillation. So
PVDF membranes, as a kind of functional material, their preferential separation process is of hi...
