Abstract

The invention relates to a method for preparing a thin polymer film with polarization performance for incident light wave on a glass surface. The method for preparing the thin polymer film with polarization performance on the glass surface is characterized by comprising the following steps of: 1) synthesizing silver nanowires by a wet chemical method; 2) dispersing the silver nanowires in solution of epoxy resin to prepare polymer filming glue solution; 3) modifying a glass substrate; 4) blowing or drawing the polymer filming glue solution to form a film; and 5) adhering the thin polymer film formed by blowing or drawing on the surface of the surface-modified glass substrate and standing the glass substrate at the room temperature for curing so as to obtain a sample. Large-sized polarized filmed glass can be obtained by the method and the obtained polarized filmed glass has obvious polarization performance.

Description

technical field [0001] The invention relates to a preparation technology of a functional polymer film, in particular to a preparation method of a polymer film capable of polarizing incident light waves on a glass surface. Background technique [0002] In today's information age, the optical fiber communication industry is developing rapidly. The service of polarizing glass in the field of optical communication began in the 1980s, and millions of pieces have been used in the preparation of optical isolators for optical communication devices, and none of them have failed. At the same time, due to its compact structure, stable performance, chemical stability and good heat resistance, it has become the preferred material for the production of optical isolators, optical fiber polarizers, optical filters, optical switches and other optical fiber communication devices. [0003] As for large-size polarizing glass, the transmittance, extinction ratio, thermal stability, mechanical s...
