23 Jul PS-TiO2 organic/inorganic composite film and preparation method thereof
Abstract
The invention discloses a PS-TiO2 organic/inorganic composite film which is provided with a PS transition layer and a TiO2 nano-particle layer sequentially from bottom to top on a PS substrate. According to preparation of the composite film, TiO2 and PS are taken as the main raw materials, tetrahydrofuran and absolute ethyl alcohol are taken as the solvents, and the PS transition layer and the TiO2 nano-particle layer are prepared on the PS substrate with a spin-coating method or a dip-coating method; a sample is subjected to heat treatment, and the PS-TiO2 organic/inorganic composite film is prepared. TiO2 in the PS-TiO2 organic/inorganic composite film is dispersed uniformly, TiO2 and the PS substrate are firmly bonded, and the composite film can be applied to the fields of photoinduced cell desorption, tissue engineering and the like. The preparation method is simple in process and easy to implement, and facilitates popularization and application.
