Abstract EN
The interaction between hydrophobically associating polyacrylamide (HAPAM) and dodecyl dimethyl betaine (BS-12) is studied through surface tension, interfacial tension (IFT), apparent viscosity, aggregation behavior, and microscopic morphologies.
Results show that surface and interface properties of BS-12 are largely affected by HAPAM.
BS-12 critical micelle concentrations are increased with the increment of polymer concentrations.
Abilities of reduced air-water surface tension and oil-water interfacial tension are dropped.
The oil-water interfacial tension to reach minimum time is increased.
HAPAM can form network structures in the aqueous solution.
Mixed micelles are formed by the interaction between BS-12 micelles and hydrophobic groups of HAPAM in aqueous solution and self-assembly behavior of HAPAM is affected.
With the increment of surfactant concentrations, the apparent viscosity, apparent weight average molecular weights (Mw, a), root mean square radius of gyration (〈Rg〉), and hydrodynamic radius of HAPAM increase first and then decline.
Moreover, microscopic morphologies of the mixed system are formed from relatively loose network structures to dense network structures and then become looser network structures and the part of network structures fracture.
