| 摘 要： | 以表面活性剂壬基酚聚氧乙烯醚硫酸钠(NPES)为对象,考察了助表面活性剂与复配表面活性剂对NPES形成微乳液体系的影响.通过比较微乳液区域(ME)在拟三元相图中所占比例,发现最优配比为m(NPES):m(DBSA)=1:1,m(复配表面活性剂):m(正丙醇)=1:3,此时形成微乳液区域面积最大,占57%;用电导率法与动态光散射(DLS)分析微乳液结构,结果表明,当w(H2O)＞60%时,形成微乳液为O/W型,粒径为34 nm;该体系对温度不敏感.

| Abstract: | Preparation and characterization of microemulsions(ME) with sodium nonylphenol ethoxylate sulphate(NPES) as emulsifying agent were studied.Effects of co - surfactant and blended surfactant on the formation of ME system were examined by comparing the proportion of area shared by the mono - phase ME regions in pseudo - ternary phase diagrams.Optimum mass ratio for the formation of biggest mono - phase ME regions as 57%was found as m(blended surfactant):m(n -propanol) = 1:3;while the blended surfactant is comp... |
