| Abstract: | Three kinds of polypropylene with different weight-average molecular weight and molecular weight distribution were applied to form microporous membranes by melt-extrusion,annealing,cold stretching and hot stretching method in this research.The effect of molecular weight on microporous membranes was characterized by gel permeation in chromatography(GPC),relaxation spectra,differential scanning calorimetry(DSC) and scanning electron microscope(SEM).The results show that T30S particle with weight-average molec... |
| Keywords: | polypropylene stretching microporous membranes weight-average molecular weight lamellar crystalline structure |
