摘要:以三氟丙基甲基环三硅氧烷(D 3 )、四甲基四乙烯基环四硅氧烷(D 4 )、六甲基二硅氧烷(MM)和三甲
氧基氢硅烷(TMS)为原料,经开环聚合,硅氢加成反应制得了烷氧基改性含氟聚硅氧烷(FVT);FVT 与正硅
酸乙酯(TEOS)、全氟辛基三甲氧基硅烷(POTS)进行分步水解缩聚,得到了一种纳米改性氟硅树脂(FVT-SiO 2 ),
并以 FVT-SiO 2 为成膜物质,制备了防指纹透明涂层。用 FTIR、SEM、XPS 对产物的结构、形貌及性能进行了
测试与表征,讨论了分步水解反应条件对涂层接触角的影响。结果表明:待 FVT 与 TEOS 先反应 2 h,再加入
POTS 进行分步反应, 可得到平均粒径约 150 nm,分散均匀的球状 FVT-SiO 2 。且当 w(FVT-SiO 2 )=2%、浸涂层数
为 3 层时,得到的涂层透明性良好、附着力强且疏水疏油性最佳,其水和油的接触角分别达到 138.5°、109°。

Abstract: Alkoxy modified fluorinated polysiloxane (FVT) was prepared by ring-opening polymerization
F
and hydrosilylation using 1,3,5-tris(3,3,3-trifluoropropyl)methylcyclotrisiloxane (D 3 ), tetramethylcyclotetrasiloxane
vi
(D 4 ), hexamethyldisiloxane (MM) and trimethoxysilane (TMS) as raw materials. Then, a nano-modified
fluorosilicone resin (FVT-SiO 2) was obtained via fractional hydrolysis and polycondensation of FVT,
tetraethyl orthosilicate (TEOS) and 1H,1H,2H,2H-perfluorooctyltrimethoxysilane (POTS). The transparent
anti-fingerprint coating was prepared by using FVT-SiO 2 as film forming material. The structure,
morphology and properties of the products were characterized by FTIR, SEM and XPS. The effect of
reaction conditions of fractional hydrolysis on the contact angle of coating was discussed. The results
showed that after FVT reacted with TEOS for 2 h, POTS was added for a further fractional reaction. the
spherical FVT-SiO 2 were obtained which dispersed homogeneously with a particle size of approximately
150 nm. Moreover, when the mass concentration of FVT-SiO 2 was 2% and the number of layers was 3, the
obtained coating had optimal transparency, adhesion, hydrophobicity and oleophobicity. Water and oil
contact angles reached 138.5° and 109°, respectively.
