| Abstract: | The HDPE microporous membranes were obtained by a melt-extrusion,annealing,cold stretching,hot stretching and heat setting method.The effect of roller rates and roller temperatures on the structure of the lamellae and the HDPE stretched microporous membranes was characterized by dynamic rheology,FTIR,DSC,SEM and other characterization methods.The results show that the molecular weight,molecular weight distribution and the relaxation time of the HDPE resin used in this experiment can meet the requirements of... |
