Abstract A series of meglumine-based polysiloxane surfactants, (PSim-n) with different numbers of meglumine branches were prepared. The formed surfactants were characterized by FT-IR and NMR techniques. Physiochemical properties, such as surface activity, aggregation behavior, and wettability, were closely examined and used to differentiate the various samples. The findings demonstrate that PSim-n surfactants possess high surface activity and can wet-out a parafilm surface at all but extremely low concentrations. Furthermore, PSi6-4, the surfactant with the highest meglumine concentration, can form larger complex aggregates in aqueous solutions.

新型葡甲胺基聚硅氧烷表面活性剂的制备、表征和性能

摘要 制备了一系列葡甲胺基聚硅氧烷表面活性剂（PSim-n），具有不同数量的葡甲胺支链。通过FT-IR和NMR技术表征形成的表面活性剂。物理化学特性，如表面活性、聚集行为和润湿性，被仔细检查并用于区分各种样品。研究结果表明，PSim-n 表面活性剂具有高表面活性，可以润湿石蜡膜表面，但浓度极低。此外，葡甲胺浓度最高的表面活性剂 PSi6-4 可以在水溶液中形成更大的复杂聚集体。
