制备含有羧基作为反应基团的N-(1H,1H-十五氟辛基)甲基丙烯酰胺共聚物，探索表面纳米涂层材料的新方法。所有共聚物在水面上形成稳定的单分子层。这些单分子层可以转移到固体基质上，从而形成 Y 型 Langmuir-Blodgett (LB) 薄膜。使用接触角和临界表面张力测量来表征共聚物 LB 薄膜的表面。共聚物单层可以固定在通过热处理用氨基硅烷偶联剂改性的固体基质上。我们使用水接触角和 X 射线光电子能谱 (XPS) 测量来监测固定过程。 SiO2 表面上固定的单层产生纳米级的光滑表面，这是使用原子力显微镜观察到的。
N-(1H,1H-Pentadecafluorooctyl)methacrylamide copolymers containing carboxyl groups as reactive moieties were prepared to explore a novel method for surface nanocoating materials. All the copolymers form stable monolayers on a water surface. Those monolayers can be transferred onto solid substrates, thereby creating Y-type Langmuir–Blodgett (LB) films. Contact angle and critical surface tension measurements were used to characterize the surfaces of the copolymer LB films. The copolymer monolayer can be immobilized onto solid substrates that are modified with an aminosilane coupling agent through heat treatment. We monitored the immobilization process using water contact angle and X-ray photoelectron spectroscopy (XPS) measurements. The immobilized monolayer on SiO2 surface yields a smooth surface at the nanoscale, which was observed using atomic force microscopy.
