摘要
Abstract
The worm-like micelles formed by the mixture of an anionic surfactant(sodium α-olefin sulfonate,AOS)and a zwitterionic surfactant(lauramidopropyl hydroxysulfobetaine,LHSB)as induced by Mn2+ions were studied.The influencing factors studied included the mass ratio between the two surfactants,the mass fraction of Mn2+,the mass fraction of surfactants,and the temperature.The results showed that,the viscosity of the surfactant solution first increased and then decreased as the mass ratio of AOS∶LHSB was increased and the mass fraction of Mn2+was increased.The zero-shear viscosity of the system exhibited an exponential increase with increasing mass fraction of surfactants.The viscosity measurement was conducted at 25℃.The maximum viscosity was obtained when the mass ratio of AOS∶LHSB was 3∶7,and the optimal Mn2+content was 0.5％when the mass fraction of surfactants was 2％(the zero-shear viscosity at this optimal condition was measured to be 9 030.9 mPa·s).The morphology of the micelles in solution was observed using Cryo-TEM,revealing long worm-like micelles with a tight network structure and good linear viscoelasticity.The mass fraction of surfactants and the presence of Mn2+were found to have significant influence on the formation of worm-like micelles.This study could provide important additional information for the preparation of worm-like micelles using mixed anionic-zwitterionic surfactant system.关键词
