Liquid paraffin-in-water emulsions stabilized by Laponite RD clay particles modified with short-chain aliphatic amines (diethylamine, DEA or triethylamine, TEA) were prepared in the absence of electrolytes. The formation and stability of the emulsions were investigated by macroscopic and microscopic observations, contact angle, zeta potential and rheology measurements. The hydrophilic Laponite particles...
Liquid paraffin–water emulsions were prepared which were stabilized by Laponite particles in situ modified with poly(oxypropylene)diamines in the absence of electrolytes. First, the characteristics of the Laponite dispersions in the presence of increasing concentrations of diamines were studied in detail. Infrared absorption spectra and zeta potential measurements confirm the adsorption of diamines...
