为了提高环氧树脂涂层的疏水性和耐腐蚀性，设计了一种具有环氧基团的无溶剂氟化聚丙烯酸酯（PFEMA）来对环氧树脂进行改性。采用红外光谱（FT-IR）、扫描电镜（ FESEM）、水接触角（CA）、电化学阻抗谱（ EIS）等测试方法研究了无溶剂氟化聚丙烯酸酯改性环氧树脂涂层的结构和性能。结果表明：随着无溶剂氟化聚丙烯酸酯用量的增加，涂层的水接触角从 69°升高至 115°；与纯环氧树脂涂层相比，氟化聚丙烯酸酯 /环氧树脂涂层的低频阻抗模量更高。此外，随着氟化聚丙烯酸酯在环氧树脂中用量的增加，涂层腐蚀速率减小，在 3. 5%NaCl溶液中浸泡 15 d后复合涂层仍有良好的保护效果。因此，引入氟化聚丙烯酸酯可以显著增强环氧树脂的防腐性能。

In order to improve the hydrophobicity and corrosion resistance of epoxy resin coatings，a solvent-free fluorinated polyacrylate（PFEMA）with epoxy groups was designed.The structure and properties of solvent-free fluorinated polyacrylate modified epoxy resincoatings were investigated using infrared spectroscopy，scanning electron microscopy（FESEM）water contact angle（CA），and electrochemical impedance spectroscopy（EIS）. The resultsshowe，d that with the increase of the amount of solvent-free fluorinated polyacrylate，the water contact angle of the coatings increased from 69° to 115°；Compared with pure epoxy resin coatings，fluorinated polyacrylate/epoxy resin coatings had higher impedance modulus values. In addition，with the increase of the amount of fluorinated polyacrylate in epoxy resin， the corrosion rate decreased，and the composite coating still had good protective effect after soaking in 3. 5%NaCl solution for 15 days. Therefore，the introduction of fluorinated polyacrylate could significantly enhance the corrosion resistance of epoxy resins.
