On the role of surfactants in emulsions and foams
Abstract
, when surfaces begin to matter. I started my research with surface light scattering and surface rheology investigations. The light scattering technique allows measurements of low interfacial tension systems, and led me to investigate microemulsions. After this work, I used my knowledge in surface rheology to investigate emulsions and foams, which are not thermodynamically stable, in contrast with microemulsions. The work is still ongoing, in particular to reach a better understanding of coalescence of bubbles and drops. I will show how interesting it is to use knowledge on surface layers at macroscopic interfaces to better understand microemulsions, emulsions and foams. I conclude with considerations on the perspectives of the research field.
