Abstract Special wetting surface with hydrophilic and oil-repellent characteristic is successfully prepared by treating hydrophilic PEGylated surface with CF4 plasma. Wettability and structure of the modified PEGylated polymer surfaces are investigated by contact angle (CA) measurements and X-ray photoelectron spectroscopy (XPS). The results of contact angle measurements show that water CA and hexadecane CA have different dependences with CF4 plasma treating time. After a 5 min treatment with CF4 plasma, the difference between water and oil CA reaches a maximum value on the modified PEGylated surface, wherein water and oil CA is 30.7° and 60.7°, respectively. We believe the technique can be further used for construction of textiles with anti-contamination and easy-decontamination properties.

通过 CF 4 等离子体处理制造亲水拒油表面

摘要 用CF4等离子体处理亲水性聚乙二醇化表面，成功制备出具有亲水拒油特性的特殊润湿表面。通过接触角 (CA) 测量和 X 射线光电子能谱 (XPS) 研究了改性聚乙二醇化聚合物表面的润湿性和结构。接触角测量结果表明，水 CA 和十六烷 CA 对 CF4 等离子体处理时间具有不同的依赖性。用CF4等离子体处理5分钟后，水和油CA之间的差异在改性PEG化表面上达到最大值，其中水和油CA分别为30.7°和60.7°。我们相信该技术可进一步用于构建具有抗污染和易去污特性的纺织品。
