Microporous membrane with controllable pore closure, and preparation method and application thereof |
| abstract |
The invention relates to the technical field of microporous membranes, in particular to a microporous membrane with controllable pore closure and a preparation method and application thereof. The microporous membrane is composed of two or more polyolefin raw materials with different melting points; Olefin raw materials include polyethylene or polypropylene; the difference between the melting points of any two polyolefin raw materials is above 3°C; among them, the content of the raw material with the lowest melting point accounts for 15%-75% of the total polyolefin components, and the melting point is the highest The content of the raw material components accounts for not less than 10% of the total polyolefin components. |
