In order to improve the antifouling ability of the base material, a fluorine-free superhydrophobic composite coating was prepared on the surface of the substrate. In this work, the Silica (SiO2) micro-nanoparticles were modified by hexadecyltrimethoxysilan (HDTMS). Subsequently, the modified SiO2 micro-nanoparticles were blended with organic silane. Finally, a stable fluorine-free hydrophobic composite coating on the surface of the substrate was prepared via the hydrolysis and polymerization of organic silane on the modified SiO2 micro-nanoparticles. The chemical compositions, morphology and hydrophobic properties of the coatings were characterized by Fourier Transform Infrared Spectrum (FTIR), Thermogravimetric analyses(TGA) , Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), and water contact angle (WCA) measurements, respectively. The results show that the composite coating surfaces had rough micro-nano scale structure, with excellent self-cleaning properties and wear resistance. Compared with the coating without the abrasion treatment, the contact angle of the coating with an abrasion treatment increased from 151° to 161°.
