摘要：
Cetyltrimethylammonium bromide (CTAB)/potassium bromide (KBr) micellar system has been used as a viscosity probe to study the inclusion complexation between beta-cyclodextrin (beta-CD) and CTAB. Viscosity measurements show that the inclusion complexation between beta-CD and CTAB may cause the breakdown of CTAB/KBr wormlike micelles, resulting in the decrease of the solution viscosity. The viscosity minimum at C(beta-CD)/C(CTAB)=2 indicate the molecular ratio of host molecule to guest molecule is 2:1 in the beta-CD/CTAB inclusion complex.
