Shear Stability of Emulsions in the Presence of Co-Surfactants with Various Chain Length of Tail

DOI

High internal phase aqueous-in-oil emulsions prepared by oil-soluble polyisobutylenesuccinicanhydride (PIBSA) with a water-soluble co-surfactant n-alkylpolyacrylamide (PAM) stabilizes the emulsions at higher shear rates. Shear causes reversible aqueous droplet deformation and also droplet size reduction. The c new surface created is covered by fast adsorption of PAM from the aqueous phase keeping reverse micelles concentrations in the oil phase at 25 °C constant. It is proposed to extend previous LOQ Shear-SANS measurements with different PAMs having different chain length in the tail. The solubility and surface behaviour of PAMs changes significantly with tail architecture and with temperature. This will shed light on the surfactant competition at the oil-water interface and on emulsion instability.
