The results showed that the viscosity of the polymer solution increased with addition of SDBS and reached to a maximum value, then decreased with further addition of SDBS. The surface tension of the mixture solution decreased with the increase of SDBS concentration. The results have been discussed.展开更多

The results show the relationship between the synergism of surfactants and the molecule exchanging energy. Through the parameter of molecule interaction( β s), the value of the molecule exchanging energy can be obtained by equation ε =2.3×10 -24 β s T that has been examined with six typical surfactant systems.展开更多
