| 摘 要： | 通过表面张力法和负染色电镜法分别从两个方面研究了二甲基亚砜 ( DMSO)对十六烷基三甲基溴化铵 ( CTAB)胶束形成的影响。研究结果表明 ,DMSO的加入使得 CTAB水溶液表面张力曲线出现双 CMC;从负染色电镜实验可以观察到 ,在 DMSO影响下 CTAB体系的第二 CMC区域出现了棒状胶束

| Abstract: | The effect of dimethyl sulphoxide(DMSO)on micelle conformation of hexadecyltrimethylammonium bromide(CTAB)was studied by means of surface tension and negative staining TEM measurements. The results show that CTAB solution has two critical micelle concentration(CMC)values due to the effect of DMSO. The appearance of the second CMC of the CTAB/DMSO/H 2O system may be attributed to a transition process from sphere like micelle to rod like micelle. |
