Title:

POROUS POLYMER MEMBRANE, METHOD FOR PRODUCING SAME, AND METHOD FOR MANUFACTURING STAMPER USED FOR PRODUCTION OF SAME

Document Type and Number:

WIPO Patent Application WO/2007/023960

Kind Code:

A1

Abstract:

Pores of an anodized porous alumina having a porous surface structure are filled with a material and then the anodized porous alumina is dissolved and removed, thereby forming a stamper which is made of the material and has a reverse structure of the surface structure of the alumina. By transferring the reverse structure of the stamper to a polymer, there is produced a porous polymer membrane having the surface structure of the alumina. Consequently, a large-sized porous polymer membrane having a surface structure, wherein pores of a uniform size are formed orthogonal to the membrane surface, can be produced without requiring a complicated process.
