Polyolefin Microporous Membrane and Manufacturing Method Thereof |
| abstract |
A polyolefin microporous membrane formed of fine fibrils comprising a polyolefin (A) or a polyolefin composition (B) containing a weight average molecular weight of 5 × 10 5 or more, having an average pore diameter of 0.05 to 5 μm, The polyolefin microporous membrane is characterized in that the ratio of the crystal lamellar with an angle Θ of the polyolefin with the crystal lamellar of 80 to 100 ° is 40% or more in the cross section in the machine direction and the cross section in the axial direction perpendicular to the machine direction. to provide. In addition, a solution of 10 to 50% by weight of (A) or (B) and 50 to 90% by weight of a solvent is extruded to obtain a gel composition, which is heat-fixed at a specific temperature range without stretching or stretching the gel-like composition. Then, it provides a method for producing a polyolefin microporous membrane, characterized in that the solvent is removed. |
