Abstract
A thermal protocol has allowed us to produce translucent O/W emulsions comp osed of nanodroplets. By means of a static light scattering analysis, we sh ow that the interaction potential existing between nanodroplets is practica lly a hard sphere interaction potential. Dynamic light scattering measureme nts bring us to study the steric effect induced by the surfactant molecules which are adsorbed at the water/oil interface. We confirm that nanodroplet dynamic coalescence rates are slowed down when the surfactant molecular we ight is high. (C) 1999 Elsevier Science B.V. All rights reserved.
