The transparent SiO2/silicone resin was prepared with tetraethoxysilane(TEOS) and organosiloxane as the main materials by the sol-gel method, then the silicone/amine hybrid hard film was prepared on polycarbonate (PC) by adding amine resin. The effects of the proportion of amine resin on the properties of hybrid hard film were discussed. The structure, morphology and transmittance of the hybrid coating were characterized by FTIR, UV, TG, SEM and particle size analyzer etc. The results show that the distribution of the hybrid resin particle size is about 162.5 nm. The alkali resistance of the hybrid film can be significantly improved by adding a small amount of amine resin. After the hybrid film is dipped in the alkali solution for 24h, its light transmittance is still up to 90.7%, and can improve the transparency of PC. When mass percent of amine resin to silicone resin is 2%, the adhesion strength of hybrid film to PC sheet is 1 grade, and pencil hardness is 2H; After heat-treated at 120℃, the hybrid film is smooth, homogenous and densification; However, the thermal stability of the hybrid film is lower slightly than that of the SiO2/silicone hard film.
