摘要： 将正硅酸乙酯（TEOS）、1,2-双（三乙氧基硅基）乙烷（BTESE）以及全氟辛基三乙氧基硅烷（POTS）通过水解缩合反应,制得纳米杂化氟硅防指纹剂TBF-SiO₂。通过红外光谱（FT-IR）、紫外-可见分光光度计、热重分析仪（TG）、场发射扫描电镜（FE-SEM）等仪器对其分别进行了结构表征、透光率及热性能分析和微观形貌观察等。结果表明:当TBF-SiO₂涂层的应用温度在25~200℃之间、n（POTS）∶n（TEOS）=3∶10、TBF-SiO2的质量分数为0.6%、喷涂层数为2层时,得到的涂层热稳定性和透明度良好、附着力强且疏水疏油性最佳,其水和油接触角分别达到了121.6°、101.7°。经过场发射扫描电镜（FE-SEM）可观察到规则且粗糙不平的类似于荷叶表面的微纳米级结构,实现了无机粒子和低表面能材料在玻璃表面的有机结合。

Abstract: A nano-hybrid fluorosilicone anti-fingerprint agent TBF-SiO, was synthesized by using tetraethyl orthosilicate ( TEOS), bis (triethoxysilyl )ethane (BTESE) and perfluorooctyl triethoxysilane (POTS) as raw materials via hydrolysis-condensation. The structure, light transmittance and thermal performance of the TBF-SiO2 were characterized by FT-IR, SEM, TEM, TGA and UV-visible spectrophotom. The results showed that when the TBF-SiO₂ coating was exposed to the temperature between 25℃and 200 ℃, the molar ratio of POTS to TEOS was 3: 10, the mass ratio of TBF-Si0₂ was 0. 6%, and two layers was sprayed, the coating gave good thermal stability,transparency, adhesion, hydrophobic/oleophobic properties. For instance, the water and oleo contact angles reached 121. 6° and 101.7°.The field emission scanning electron microscope(FE-SEM) indicated that the regular and rough micro/nano-level structure similar to the lotus leaf surface was formed, which achieved the organic combination of inorganic particles and low surface energy materials on surface of glass.
