A organic-inorganic hybrid modification fluorosilicone resin（AFPS@SiO₂） was prepared by ring-opening polycondensation， hydrosilylation and hydrolytic copolycondensation of 1，3，5-tris（3，3，3-trifluoropropyl）methylcyclotrisiloxane（D3F）， octamethyl-cyclotetrasiloxane（D₄）， and 1，1，3，3-tetramethyldisiloxane（D₂^H）. Then AFPS@SiO₂ was applied to the surface of PET film to construct a transparent high temperatureresistant and anti-sticking coating. The structure，morphology，and properties of the production were characterized by FT-IR，SEM，XPS and TGA. The effects of the molar ratio［n（D）∶n（DF）］ on the water contact angle，peeling force，adhesion，hardness and light transmittance of the coating were discussed. The results show that when the molar ratio［n（D）∶n（DF）］ was 3∶2，the comprehensive performance of the anti-sticking coating was the best. Its water contact angle was 108. 1°，peeling force was 0. 029 N/cm，the adhesion was grade 1，the hardness was 4H，and light transmittance was 90. 0%. This study provided apreparation idea of transparent high temperature resistant and anti-sticking coating for PETfilm，which indicated certain application value.
