PROCESS FOR PRODUCING COLUMNAR STRUCTURE HAVING TWO-STAGE HIERARCHICAL STRUCTURE

摘要

This invention provides a process for artificially producing a structure imitating a fine two-stage hierarchical structure as seen in the sole of a house gecko in a simple and easy manner. The process for producing a two-stage hierarchical columnar structure comprises step (1) of filling pores in a porous film on a base material with a resin, step (2) of curing the resin to form a columnar structure part, step (3) of plasma etching the end part of the columnar structure part to form a two-stage hierarchical columnar structure part, and step (4) of removing the porous film from the base material.
