High internal phase water-in-oil emulsions can be efficiently stabilised by polymer amphiphiles for a static emulsion, and also show high shear stabillity even at elevated temperatures. In this LOQ application the mechanisms of shear deformation and stabilisation of these emulsions as a function of temperature will be investigated. The insight into the shear stabilisation mechanisms, and in particular to the role that polymer surfactant reverse micelles in the continuous oil phase plays in these mechanisms, will be used to elucidate the interplay between static emulsion stability and the ability to resist dynamic perturbations.
