| 摘 要： | 通过酯化反应制备了一种含有苯环间隔基的含氟丙烯酸酯单体,随后采用自由基聚合合成了新型含氟聚合物PFBA和对比样品聚合物PFA,采用傅里叶红外光谱和氢核磁光谱验证了其化学结构,通过接触角测试研究间隔基对聚合物表面润湿性能的影响。结果显示,PFA膜的初始接触角为117.4°,PFBA膜的初始接触角为109.9°;随着接触时间的延长,PFA膜的接触角迅速下降至60.0°,而PFBA膜中的苯环间隔基为氟烷基提供了稳定的分子构象,使其接触角几乎未降低。

| Abstract: | A fluorinated acrylate monomer with phenyl spacers was prepared by esterification, then a novel fluorinated polymer PFBA and a contrast sample PFA were synthesized by free radical polymerization. The chemical structures were verified by Fourier infrared spectroscopy and nuclear magnetic spectroscopy, and the water contact angle measurement was adopted to investigate the effect of spacer on their surface wettability. Results showed that the initial water contact angle of PFA film was 117. 4°, and it was 109. 9° for the PFBA film. However, the water contact angle of PFA film quickly dropped to 60. 0° with the extension of contact time. Conversely, the phenyl spacer in PFBA film provided a stable molecular conformation for the fluoroalkyl groups, resulting stable water contact angles. |
