【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（D_H²）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。更多还原

【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（D_H²）.Then AFPS@SiO₂ was applied to the surface of PET film to construct a transparent high temperature resistant 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 a preparation idea of transparent high temperature resistant and anti-sticking coating for PET film,which indicated certain application value.更多还原
