METHOD FOR PRODUCING OPTICAL MEMBER AND OPTICAL MEMBER FORMED BY THE PRODUCTION PROCESS

摘要

A method for producing an optical member from a nanocomposite material which includes a thermoplastic resin containing inorganic fine particles is provided. The method includes: a first step of preparing in a solution the thermoplastic resin containing the inorganic fine particles; a second step of drying and solidifying the solution containing the prepared thermoplastic resin to produce the nanocomposite material having a specific surface area (surface area/volume) of 15 mm-1 or more; and a third step of heat-compressing the produced nanocomposite material to form the optical member in a desired shape.
