Title:
FUNCTIONAL RESIN AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2013/176267
Kind Code:
A1
Abstract:
Resin A and substrate resin B are heated to a temperature at which at least some of both resins is melted, and the resins are kneaded together in an injection molding device. A resin product is then created in which resin B is molded in a columnar structure or lamellar structure inside resin A. This resin molded product is immersed in a solution which is more highly erosive of resin A than resin B, and an uneven shape is formed in the surface of resin B by dissolving the other resin. As a result, a resin structure and a manufacturing method for this resin structure can be provided in which unevenness of different shapes, densities and depths can be formed at low cost, and in which wettability and optical control of the molded product can be finely adjusted and maintained over a long period of time.
