摘要：

A thermal protocol has allowed us to produce translucent O/W emulsions composed of nanodroplets. By means of a static light scattering analysis, we show that the interaction potential existing between nanodroplets is practically a hard sphere interaction potential. Dynamic light scattering measurements 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 weight is high. (C) 1999 Elsevier Science B.V. All rights reserved.
