摘要: 以阴离子表面活性剂芥酸钾(KEU)与有机反离子三羟乙基苄基氯化铵(BTHEAC)通过自组装形成的蠕虫状胶束为主要研究对象,苯乙烯与N,N-孪尾取代丙烯酰胺(DiCnAM)为可聚合单体,偶氮二异丙基咪唑啉盐酸盐(VA-044)为引发剂,在一定温度下,合成了系列增溶单体并聚合的蠕虫状胶束,通过黏度法研究了该合成条件对蠕虫状胶束表观黏度的影响。结果表明,当单体增溶并聚合后,蠕虫状胶束表观黏度显著增大。当苯乙烯的浓度为0.02mol/L、摩尔比n(KEU):n(BTHEAC)=5:3、n(苯乙烯):n(DiC8AM)=5:2时,合成的蠕虫状胶束表观黏度最大,为1320mPa·s,明显大于KEU/BTHEAC蠕虫状胶束的表观黏度,且耐温性能良好。

Abstract: The wormlike micelles were prepared by self-assembled with anionic surfactant Potassium erucic(KEU) and organic counterion three hydroxyethyl benzyl ammonium chloride(BTHEAC). Styrene and twin tail hydrophobic monomer N, N-twin tails substituted acrylamides(DiCnAM) as monomers. 2, 2'-Azobis[2-(2-imidazolin-2-yl)propane] dihydrochloride (VA-044) acted as initiators. The new wormlike micelles, solubilized and polymerized, were synthesized at a certain temperature. The properties of wormlike micelles were measured by viscometer. The results showed that the wormlike micelles added with monomers and polymerized, the concentration of styrene was 0.02mol/L, the molar ratio of n(KEU):n(BTHEAC)=5:3, n(styrene):n(DiC8AM)=5:2, the best apparent viscosity of the wormlike micelles was obtained, which is 1320mPa·s, higher than the apparent viscosity of KEU/BTHEAC wormlike micelles, and it was also good at high temperature.

Key words: surfactants, wormlike micelles, apparent viscosity
