In recent years, porous PP membrane was mainly prepared by melt-stretching technique. This technique can produce PP membrane with high mechanical strength and low cost. Melt-stretching consists of four main processes: (a) melt-extrusion process, (b) annealing, (c) stretching, and (d) heat-setting. The parameters of each process are fundamental to determine the structure and performance of the porous PP membrane, thus the selection of appropriate parameters of each process is very important. In this work, the effect of annealing and stretching parameters on the structure and performance of porous PP membrane was investigated. The PP films was were annealed at various temperatures and then stretched under different stretching steps, including cold stretching, hot stretching, and combination of cold and hot stretching. In addition, the stretching ratio was also varied to study its effect to the pore structure and dimensional stabilityof PP membrane.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]High mechanical strength,Hot stretching,Melt extrusion process,Polypropylene hollow fiber membrane,Polypropylene membrane,Semi-crystalline polymer,Stretching ratios,Structure and performance[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Annealing,cold stretching,hot stretching,polypropylene membrane,stretching ratio[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/2053-1591/ab0797[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
