| titleOfInvention | Semi-crystalline polymer microporous membrane and its manufacturing method |
| abstract | The microporous membrane according to the present invention comprises a bubble region having irregularly distributed cross-sections of three-dimensionally interconnected sheets produced by phase separation between semicrystalline polymer resin and diluent, and by diluent. Obtained by extracting the diluent after stretching the semi-crystalline polymer resin sheet in which the swelled amorphous region is present; The bubble area has an irregular size and structure, the average diameter of the cross section is 0.01 μm or more, 2 μm or less, connected in three dimensions to penetrate the thickness of the resin sheet, and the volume ratio of the entire resin composition is 10% or more and 40% or less. The swelled and swollen amorphous region is a region in which the swelling ratio is 200% or more and is formed during the stretching process to form micropores connected in three dimensions to make pores having an average diameter of 0.01 µm or more and 1 µm or less.n n n Semicrystalline polymer, microporous membrane |
