Due to its properties of reducing surface energy and preventing adhesion, 1H,1H,2H,2H-perfluorododecyltrichlorosilane can be used as a superhydrophobic modified coating on the surface of polymer films. In this study, tetraethylorthosilicate was firstly polymerized to prepare silica microparticles (SiO2 MPs). Then SiO2 MPs were dispersed in heptane as a continuous phase and reacted with 1H,1H,2H,2H-perfluorododecyltrichlorosilane (FTS) to generate FTS-SiO2 MPs to obtain fluorine-conjugated SiO2 MPs. Finally, the FTS-SiO2 MPs are prepared by the "throwing stones " technique to prepare super-hydrophobic thin coatings and deposited on the surface of various polymer films. The results show the adhesion of FTS-SiO2 MPs to thin films, high durability of coatings, and good self-cleaning properties, which demonstrate their potential in various applications. Furthermore, the developed superhydrophobic coating can be transparent if desired. For example, thin superhydrophobic coatings on polycarbonate (PC) films have been shown to have excellent optical and self-cleaning properties for specific practical applications.
