Abstract

The invention discloses a preparation method of a PS-TiO2-ATP organic / inorganic composite film. Polystyrene (PS), titanium dioxide (TiO2) and attapulgite (ATP) are taken as main raw materials, and cyclohexane (C6H12) is taken as solvent. The preparation method comprises the steps of: firstly, dissolving PS in C6H12 to obtain a solution A; secondly, dispersing nanometre TiO2 / ATP composite power bodies in the C6H12 to obtain a solution B; thirdly, ultrasonically mixing the solutions A and B to obtain a solution C; fourthly, pouring the solution C on a cleaned sheet to be spin coated into the film; and finally, drying the film by airing naturally, and carrying out heat treatment at the temperature of 100 to 110 DEG C to prepare the PS-TiO2-ATP organic / inorganic composite film. The film can be applied to the fields of photocatalysis, solar energy film batteries, photoelectric conversion, thermoelectric conversion, electromagnetic shielding, microwave absorption, and the like.
