β-CD对SDS胶束生成与特性的影响
Effect of β-CD on the Formation and the Properties of SDS Micelle
摘要
Abstract
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.关键词
