| titleOfInvention | Vinylidene fluoride resin porous film, its production method, and its production method |
| abstract | The average diameter of the mesh-shaped resin fibers in a portion of 10 μm in thickness continuous from one surface measured by a focused ion beam / scanning electron microscope is 100 nm or less, the porosity A1 is 60% or more, and the one surface side surface pore P1 is Provided is a vinylidene fluoride resin porous film, which is 0.3 m or less. In addition to the small surface porosity suitable for the treatment of the filtered water, the porous membrane has a very thin mesh-like resin fiber, and has a very high porosity surface layer on the surface of the water to be treated. Become. The porous membrane is also polyester-based having compatibility with a vinylidene fluoride resin having a large molecular weight and providing a kneaded product with vinylidene fluoride-based resin to a crystallization temperature almost equivalent to the crystallization temperature of vinylidene fluoride-based resin alone. The molten extruded membrane obtained by adding a relatively large amount of plasticizer is preferentially cooled from one side to be solidified, and then produced by a method of extracting the plasticizer, partially wetting the surface, and stretching. |
