PHOTOCHROMIC PLASTIC OBJECT

摘要

The invention relates to a photochromic plastic object which is composed of a transparent polymeric synthetic material, into or onto which at least one substantially mesoporous inorganic host structure that is provided with one or several embedded organic photochromic dye molecules is introduced or applied so as to form a photochromic nanocomposite material. According to the invention, photochromic nanocomposite particles or photochromic nanocomposite structures are used for creating color as opposed to prior art in which photochromic organic dyes are added to the monomer mixture/prepolymer of synthetic glass in a molecular form.
