Abstract

The invention discloses a method for preparing a styrene grafted silicon dioxide superhydrophobic thin film, which comprises: firstly, adding tetraethoxysilane into mixed solution of a catalyst and an alcohol solvent to obtain nano silicon dioxide spheres by reaction; secondly, adding the nano silicon oxide spheres into the alcohol solvent, and adding a silane coupling agent and the catalyst to obtain vinyl modified nano silicon oxide spheres; and finally, adding the vinyl modified nano silicon oxide spheres into a benzene or ketone organic solvent, adding an initiator and a styrene monomer in turn to obtain the styrene grafted silicon dioxide spheres, dispersing the styrene grafted silicon dioxide under ultrasonic waves, and preparing the styrene grafted silicon dioxide by using an organic or inorganic material as a substrate and by a coating method. The preparation process is simple and high in repeatability, the cost is low, and the promotion is more convenient.
