Interaction of Preformed Particle Gel and Sodium Dodecyl Sulfate

Abstract

The adsorption of anionic surfactant of sodium dodecyl sulfate (SDS) onto preformed particle gel (PPG) and the effects of SDS on the swelling ratio of PPG were combined. The effects of anionic surfactant sodium dodecyl sulfate on the rheology of preformed particle gel were also studied by using steady shear and oscillatory shear rheological experiments. The interaction mechanism of SDS and the rheology of preformed particle gel was discussed. The results show that the adsorption of SDS increases and the swelling ratio of PPG first decreases and then keeps stable with the increase of SDS. The preformed particle gel exhibits shear-thinning property and its viscosity is significantly influenced by SDS at lower shear rate. With the increase of SDS concentration, the yield stress of the preformed particle gel decreases and the storage modulus first decreases and then increases.
