测定了新型Gemini表面活性剂(C6-2-C6
C8-2-C8)的临界胶束浓度和相对粘度
讨论了表面活性剂溶液浓度、疏水链长度、无机盐对表面活性剂溶液粘度的影响.研究结果表明:Gemini表面活性剂临界胶束浓度比十二烷基硫酸钠(SDS)低1
2
个数量级
随着疏水链长度的增加表面活性剂的CMC降低.表面活性剂溶液浓度对Gemini表面活性剂的粘度影响非常明显
对普通的十二烷基磺酸钠(SDS)表面活性剂的粘度影响不大.无机盐的加入使Gemini表面活性剂的粘度先增大后减小.用透射电镜(TEM)观察了溶液的聚集体形态
C8-2-C8Gemini表面活性剂能形成直径80~100nm的囊泡.
The critical micelle concentrations(CMC)and viscosities of the novel Gemini surfactants were determined.The effect of concentration
length of the carbon chain and inorganic salt on viscosity was discussed.The results indicated that CMC of the Gemini was lower 1
2
orders of magnitude than that of sodium dodecyl sulfate(SDS).The CMC was decreased as the increase of the length of carbon chain.The effect of concentration on the viscosity for Gemini surfactants was larger than that for SDS.With addition of inorganic salts
the viscosity of Gemini surfactants increased initially and then decreased.The aggregate morphology of Gemini surfactant in solution was observed by TEM.The vesicle whose diameter was from 80 to 100 nm was founded in C8-2-C8.
