Micron scale rough structures of glass substrate was prepared by painting epoxy acetone solution and silica(SiO2) suspension.Superhydrophobic duplex-treated film was fabricated by deposited perfluorodecyl trichlorosilane self-assembled monolayers on the microstructures.Scanning electron microscope,contact angle measurement and high-speed camera system were used to analyse the surface properties and the wettability of specimens.And ultraviolet-visible spectrum analyzer was used for film transmittance measurement.The results indicated that the microstructures constructed by epoxy resin and nanoparticles played an important role in the construction of superhydrophobic surfaces.The composite film surface exhibited low adhesion and low rolling angle.The contact angle of the film gradually increased with the increase of the silica content to become stable.The transmittance of the film layer shown decreasing trend with the increase of the silica content,and the light transmittance was above 75%.
