Abstract

The invention relates to a preparation technology of a thin functional polymer film, in particular to a method for preparing a thin polymer film with polarization property on the surface of glass, which is characterized by comprising the steps of: 1, synthesizing a silver nanowire by using a wet chemical method; 2, selecting the silver nanowire and absolute ethyl alcohol according to the proportion of the silver nanowire and the absolute ethyl alcohol of (20-25)mg:7mL, adding the silver nanowire into the absolute ethyl alcohol to prepare a suspension; selecting epoxy resin according to the proportion of the silver nanowire and the epoxy resin of (20-25)mg:25g, then adding the suspension into the epoxy resin, stirring for 5-10min, adding an organic amines curing agent which is 15-30 percent of the mass of the epoxy resin, stirring for 10-20min to obtain a polymer glue solution containing the silver nanowire; and 3, immersing a glass substrate into the polymer glue solution, then pulling a coating film, standing and curing at room temperature to obtain coated glass with polarization property. The method can obtain the coated glass with large size, and the prepared coated glass has remarkable polarization property.

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...
