Title:
多孔質フィルム及びその製造方法
Document Type and Number:
Japanese Patent JP4451410
Kind Code:
B2
Abstract:
A honeycomb film as a porous film includes a support and a honeycomb film as a porous film formed on the support. A polymer solution is applied to the support to form a wet layer, and water droplets are formed in the wet layer. Thereafter the water droplet is dried to form pores in the wet layer, such that the wet layer may be the honeycomb film. Thus the honeycomb film is obtained, and when it is piled or wound for storing, it is not damaged or torn.
