【摘要】 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 .更多还原

【Abstract】 The effect ofβ 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 ofβ CD between the micellar phase and the continuous water phase. The results show that the distribution ofβ CD in the micellar phase increases and the diffusion coefficient D and the aggregation number N will decrease with addedβ CD when the concentration ofβ CD is lower.The distribution ofβ CD in the continuous water phase increases and the influence ofβ CD on D and N are reduced remarkably when the concentration ofβ CD is higher.When the SDS concentration is less than the first CMC ,the inclusion compounds ofβ CD with SDS monomer form in the molecular ratio of 1:1 .Mixed spherical micelle could be prepared in the molecular ration of 1:8 forβ CD/SDS when the SDS concentration is higher than the first CMC.更多还原
