Outline
Chemical etching was used to etch the surface of soda lime silicate glass with TEOS as a precursor to prepare nano-silica particles and CTAB to control the degree of agglomeration, and then the chemically etched glass surface was sprayed with nano-silica particles with different agglomeration degrees to construct a multi-level micro-/nano-structure, which was further modified with PFTS to obtain a superhydrophobic glass surface. The micro-morphology and wettability of the coating were characterized by scanning element microscopy and contact angle measurement. The results show that the prepared glass surface has the superhydrophobic properties, and the water contact angle of 156.13°±2° can still maintain after 50 cycles of rubbing with 600 grit sandpaper. The superhydrophobicity of the glass surface is attributed to a combined effect of the presence of low surface energy substance PFTS and the surface spherical structure, and its better wear resistance is since the rigid micron-scale rough structure of the glass surface and the structure formed by the sprayed nano-scale silica particles on the glass surface are interlaced, thus forming a more wear-resistant micro-/nano-structure.
