INTERACTION BETWEEN CATIONIC-ANTONIC AND ZWITTERIONIC SURFACTANT IN MIXED AQUEOUS SOLUTIONS

本文研究正负离子表面活性剂与两性表面活性剂混合水溶液的表面性质,以及两性表面活性剂对正负离子裘面活性剂溶解度的影响。结果表明:(1) 两性表面活性剂的加溶作用,有助于正负离子表面活性剂的溶解;(2) 加入两性表面活性剂的量适当,混合溶液基本保持原正负离子表面活性剂的表面活性;(3) 正负离子表面活性剂与两性表面活性剂在表面层和胶团中分子间的相互作用比正负离子表面活性剂与非离子表面活性剂分子间的相互作用稍强HC-FC正负;离子表面活性剂与两性表面活性剂混合体系在表面层中有可能形成双分子或多分子层结构。Cationic-anionic surfactants have a high surface Activity, Out they are liable to precipitate as the coneetratiort is slightly over erne, so their utilities are restricted, This paper decribes their various surface properties and solubility phenomens when zwitterionic surfactant, the solubility of cationic-anionic surfactants is increased. (2) Proper amount of zwitterionic surfactant may keep the surface activitiy of the cationic-anionic surfactant essentially to be constant. (3) The molecular interation between cationic-auionic and zwitterionic surfacts is stronger that that between cationic-anionic and nonioic surfactants in both surface layer and miceile, for HC-FC cationic-anionic and zwitterionic systems the saturated adsorption film possibly have a double-or multilayer structure.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000207573600008&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701SCI(E)中国科学引文数据库(CSCD)204413-419
