摘要： 借助JC2000A静态接触角测量仪和XPS对所制备的自交联含氟乳液涂膜进行表征及分析, 分别利用实验法和基团贡献法计算涂膜的表面自由能, 探讨含氟侧链在自交联含氟乳胶膜的排列. 结果表明, 增加含氟单体的用量, 可以降低含氟聚合物涂膜的表面自由能, 但当含氟单体用量超过20.3％时, 涂膜的表面自由能的变化不大, 含氟乳胶膜具有良好的自我恢复性能. 进一步的研究结果表明, 含氟聚合物乳液成膜后含氟侧链在涂膜表面的排列是一种无规则排列.

关键词: 含氟侧链, 含氟乳胶膜, 排列, 自我恢复功能

Abstract: The self-crosslinking fluorine-containing latex film was attributed and characterized with Static Contact Angle Instrument and X-ray Photoelectron Spectrum(XPS), and then the surface free energy of the latex film was calculated by the use of experimentation and group contribution method respectively. The purpose is to examine the arrangement of fluorine-containing group side chains on the latex film surface. The results show that the surface free energy of the latex film can be decreased along with increase of fluorine-containing monomer amount when its amount is below 20.3％, but that when above 20.3％, variation of surface free energy of the latex film is less and the fluorine-containing latex film has a strong self-recovery capability. Further studies on the film surface show that the arrangement of fluorine-containing group side chains on the latex film surface is random and irregular.

Key words: Fluorine-containing sidechain, Fluorine-containing latex film, Arrangement, Self-recovery capability
