Rheological properties of novel viscoelastic micelle systems containing anionic-nonionic dimeric surfactant

The viscoelastic micelle systems formed by novel anionic-nonionic dimeric surfactant and conventional cationic surfactant cetyltrimethylammonium(1631) were studied. The viscoelasticity, thixotropy, flow curves and constitutive equation for the novel viscoelastic micelle systems were investigated. The results show that the micelle systems possess viscoelasticity, thixotropy, and shear thinning property. Some micelle systems possess hysteresis loops showing both viscoelasticity and thixotropy. It is proved that the flow curves are characterized by the co-rotational Jeffreys constitutive equation correctly.
