摘要
通过测定十六烷基三甲基溴化铵(CTAB)在不同温度和不同浓度的二甲基亚砜(DMSO)时的表面张力,研究了DMSO对CTAB胶束形态的影响.研究结果表明:DMSO的加入可使CTAB溶液的表面张力降低,临界胶束浓度(CMC)略减小;分子平均截面积减小;胶束形态由球状变成棒状.
The effect of dimethyl sulfoxide （DMSO） on micelle configuration of hexadecyltrimethylammonium bromide （CTAB） was studied with measuring the surface tension of CTAB at different temperatures and concentrations of DMSO. The results showed that with the increase of DMSO, the surface tension and critical micelle concentration of CTAB decreased; the molecule average areas decreased; the micelle configuration changed from spherical to clubbed.
