通过胶束的扩散系数D、聚集数N和β-CD在SDS胶束与水连续相间的分配系数P的测定,研究了β-CD对SDS胶束特性的影响.结果表明,β-CD浓度较小时,随着β-CD的加入,其在SDS胶束相中的分配增大,胶束的扩散系数D与聚集数N均降低.β-CD浓度较大时,其在水连续相中的分配增加,对SDS胶束的扩散系数D与聚集数N的影响显著降低.SDS浓度小于第一CMC,β-CD与SDS单体形成1∶1的包合物；SDS浓度大于第一CMC,β-CD与SDS形成1:8的混合球形胶束.

The effect of β-CD on the properties of SDS micelle was studied by the determination of the diffusion coefficient D and the aggregation number N of SDS micelle,and the distribution coefficient of β-CD between the micellar phase and the continuous water phase. The results show that the distribution of β-CD in the micellar phase increases and the diffusion coefficient D and the aggregation number N will decrease with added β-CD when the concentration of β-CD is lower. The distribution of β-CD in the continuous water phase increases and the influence of β-CD on D and N are reduced remarkably when the concentration of β-CD is higher. When the SDS concentration is less than the first CMC,the inclusion compounds of β-CD with SDS monomer form in the molecular ratio of 1∶ 1. Mixed spherical micelle could be prepared in the molecular ratio of 1:8 for β-CD/SDS when the SDS concentration is higher than the first CMC.
