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.
