| 摘 要： | 用表面张力及电动势法研究了C10H21N(CH3)3Br、C12H25N(CH3)3Br与C3F7CH2OH混合水溶液的表面与胶团性质。结果表明,对于阳离子表面活性剂,C3F7CH2OH的加入一方面增加表面活性,另一方面降低胶团反离子结合度。后者不同于阴离子表面活性剂/C3F7CH2OH混合体系,可归因于C3F7CH2OH略有酸性,因而具备一些类似阴离子表面活性剂的性质。

| Abstract: | The surface and micelle properties of C10H21N(CH3)3Br/C3F7CH2OH and C12H25N (CH3)3Br/C3F7CH2OH aqueous solutions are investigated by surface tension and electromorive force methods. The results show that the surface activity of solution is increased and the counterion binding degree of micelle is decreased when C3F7CH2OH is added into cationic surfactant aqueous solution. The latter differs from that of anionic surfactant/C3F7CH2OH systems, which should be due to the acidity of C3F7CH2OH. |
