摘要：

Flow (rheological) properties and dynamic viscoelasticity of concentrated solutions of a hybrid surfactant containing a fluorocarbon chain and hydrocarbon chain within a single molecule were analyzed. The results indicated that the viscosity of the hybrid surfactant solution is not proportional to the increase in its concentration, and it showed an anomalously large value around a 10 wt % solution. It was also indicated that the surfactant solution in this range of concentration behaves like a viscoelastic substance with a characteristic of rubber Like elasticity.
