以聚酯（PET）和氟硅树脂（FS）为原料，制备了具有优异耐热性和表面润湿性的氟硅改性聚酯树脂（FSP）。以1H，1H，2 H，2 H-全氟烷基三乙氧基硅烷（FTEOS）、甲基三乙氧基硅烷（MTEOS）、苯基三乙氧基硅烷（PTEOS）、二甲基二甲氧基硅烷（DMDMOS）和二苯基二甲氧基硅烷（DPDMOS）为原料，通过水解缩合反应合成了FS。采用傅里叶变换红外光谱（FT-IR）、X射线光电子能谱（XPS）和原子力显微镜（AFM）对树脂的表面化学组成和形貌进行了表征。通过接触角测量和热重分析（TGA）研究了FPS薄膜的表面润湿性和热性能。由于氟硅树脂本身具有较高的键能和较低的表面自由能，改性后的树脂具有优异的耐热性、拒水性和有机物性。对于含有50wt%氟硅树脂的FSP树脂（F5 SP 50），起始分解温度Td 10（10%重量损失）达到360 ℃，这比纯PET的起始分解温度高40 ℃。在700 °C下的残余重量也显著增加。此外，通过优化氟硅在聚酯树脂中的添加量，提高了FSP膜的疏水性、疏油性和硬度。所制备的氟硅改性聚酯树脂在高温涂料中具有很大的应用潜力。
In this work, fluorosilicone modified polyester resin (FSP) prepared from polyester (PET) and fluorosilicone resin (FS) with excellent heat resistance and surface wettability was reported. FS was synthesized by hydrolysis and condensation reaction of 1H,1H,2H,2H-perfluoroalkyltriethoxysilane (FTEOS), methyltriethoxysilane (MTEOS), phenyltriethoxysilane (PTEOS), dimethyldimethoxysilane (DMDMOS), and diphenyldimethoxysilane (DPDMOS). The surface chemical composition and morphology of the resins were determined by Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM). The surface wettability and thermal property of the FPS films were studied via contact angle measurements and thermogravimetric analysis (TGA), respectively. The modified resin displayed excellent heat resistance, water and organics repellence due to the native high bond energy and low surface free energy of fluorosilicone. For the FSP resin containing 50 wt% of fluorosilicone resin (F5SP50), the starting decomposition temperature Td10(10% weight loss) reached 360 °C, which was 40 °C higher than that of neat PET. The residual weight at 700 °C was also remarkably increased. Moreover, hydrophobicity, oleophobicity and hardness of FSP films were enhanced by optimizing the addition of fluorosilicone in polyester resin. The prepared fluorosilicone modified polyester resin has a great potential in the application of high-temperature coating.
