Titanium dioxide (TiO2) inorganic particles were surface modified by using silane coupling agent KH-570 to improve its dispersion in organic systems. The superhydrophobicity of surface modified TiO2 was characterized using FT-IR, contact angle, sedimentation tests, and SEM. And the form mechanism of the superhydrophobicity surface was also analyzed. The results showed that the hydrophobicity and dispersibility of the surface modified TiO2 particles with KH-570 were significantly improved, the surface modified TiO2 coating with KH-570 15 wt % showed good superhydrophobicity that the water static contact angle reached 152.5°.
