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.

A fine metal structure having its surface furnished with microprojections of high strength, high precision and large aspect ratio; and a process for producing the fine metal structure free of defects. There is provided a fine metal structure having its surface furnished with microprojections, characterized in that the microprojections have a minimum thickness or minimum diameter ranging from 10 nanometers to 10 micrometers and that the ratio between minimum thickness or minimum diameter (D) of microprojections and height of microprojections (H), H/D, is greater than 1. There is further provided a process for producing a fine metal structure, characterized by comprising providing a substrate having a fine rugged pattern on its surface, applying a molecular electroless plating catalyst to the surface, thereafter carrying out electroless plating to thereby form a metal layer having the rugged pattern filled, and detaching the metal layer from the substrate to thereby obtain a fine metal structure furnished with a surface having undergone reversal transfer of the above rugged pattern.
