Simulation experiments were conducted to investigate the effects of Na–montmorillonite (Na–Mt) on the emulsion stability of polymer flooding water. To study the stabilization mechanisms of Na–Mt particles in the emulsion system, the oil/water interfacial properties were investigated by measuring the zeta potential, interfacial tension and dilational viscoelasticity. The features of Na–Mt particles...
Stable foams have been generated in low concentration aqueous dispersions of hexylamine-modified Laponite particles. The particles are of primary size 30nm, modified with hexylamine molecules to render them partially hydrophobic or moderate flocculants. Infrared adsorption spectra and zeta potential measurements confirm the adsorption of hexylamine molecules on the Laponite particles. The foamability,...
