| Abstract: | The microporous membrane of ultrahigh molecular weight polyethylene(UH-MWPE) was prepared by thermally induced phase separation(TIPS).Its microstructures were controlled by changing molding conditions(polymer concentration,molecular weight, and cooling rate).The influence of the molding conditions on the crystallization property and mechanical property of the microprous membrane was also studied.The results show that the crystal degree,average pore size and porosity of UHMWPE microporous membrane decrease w... |
