Abstract
In the process of preparing poly4-methyl-1-pentene(PMP)porous membranes based on the mechanism of thermal induced phase separation,the cooling conditions directly affect the microstructure,air permeability and mechanical properties of the porous membranes.In this paper,poly4-methyl-1-pentene/dioctyl phthalate/dibutyl phthalate(PMP/DOP/DBP)blends were prepared by a twin-screw extruder,and porous membranes were extracted by ethanol organic solvent.The effects of medium,temperature and time on the crystallization,microstructure,mechanics and permeability of the porous membranes were investigated.The results showed that the prepared porous PMP membranes showed good comprehensive properties with a crystallinity of 26.8%,uniform pore size distribution with the porosity of 67.5%,tensile strength of 8.5 MPa and oxygen transmission rate of 9.1 mL/(min∙cm2)under the cooling medium of water,temperature of 25℃and time of 30 s.关键词
