The method provided by the invention can effectively promote dispersion of copper oxide, improve the effect of copper oxide in the film, and make the film surface atoms combine closely, thereby obtaining high strength.

Description

A kind of production method of black PVDF thin film
Technical field
The present invention relates to a kind of production method of film, specifically a kind of production method of black PVDF thin film.
Background technology
Along with the development of photovoltaic industry, the film requirements amount prepared with poly(vinylidene fluoride) increases severely.Generally, the film that prepared by poly(vinylidene fluoride) is mainly used in sun power backboard.This film article is water white, has suitable transmittance, and ultraviolet resistance, anti-steam have long-term work-ing life.But this film is not suitable for being used in the place needing to absorb sunlight, even if existing black thin film can contribute to absorbing sunlight, but its intensity is also poor, is unfavorable for long-time use.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of production method of black PVDF thin film, and the method contributes to obtaining the high film of intensity.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A production method for black PVDF thin film, is characterized in that comprising the following steps:
