| 摘 要： | 以聚乙二醇、全氟丁酸为主要原料,采用直接酯化的方法,合成了一系列聚乙二醇系非离子型氟碳表面活性剂——聚乙二醇全氟丁酸酯(以单酯为主,且含有少量双酯),且对其红外光谱、表面张力、临界胶束浓度、浊点进行了测试。结果表明,该类氟碳表面活性剂具有很高的表面活性,同时,随PEG链段长度的变化,其表面张力、CMC值、浊点都发生规律性的变化。

| Abstract: | A series of non-ionic PEG - based fluorocarbon surfactants called polyethylene glycol perfluorobutyrate (single ester-based with a small amount of diester) were prepared using perfluorobutyric acid and polyethylene glycol(PEG) as materials by the method of direct esterification.After purification,the structures of products were confirmed by FT-IR.Their surface activity,critical micelle concentration(CMC) and cloud point were carefully measured.The results indicate that all these fluoropolymer have extremely... |
