摘要：
以三氟丙基三甲基环三硅氧烷（ D3F）、八甲基环四硅氧烷（ D4）、四甲基二氢二硅氧烷（D2H）为原料，经开环缩聚、硅氢加成、水解共缩聚反应制得了一种有机 -无机杂化改性氟硅树脂（AFPS@SiO2），将其涂覆于 PET膜表面，制得透明耐高温防黏涂层。通过红外光谱仪（FT-IR）、扫描电镜（SEM）、 X射线光电子能谱仪（ XPS）、热重分析仪（ TGA）对目标产物的结构、形貌及性能进行表征测试，讨论了分子链节物质的量比 [n（D）∶n（DF）]对涂层水接触角、剥离力、附着力、硬度和透光率的影响。结果表明：当 n（D）∶n（DF）=3∶2时，防黏涂层的综合性能最优，其水接触角为 108. 1°，剥离力为 0. 029 N/cm，附着力为 1级，硬度为 4H，透光率为 90. 0%。提供了一种 PET膜用透明耐高温防黏涂层的制备思路，为后续研究提供了参考。

Abstract: 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（D2H）. 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.
