Title

Interactions of mixed nonionic-ionic surfactant micelles determined by SANS

Abstract

The aim of this work is to resolve the structure and interactions in mixtures of nonionic-ionic surfactant micelles (nonionic: Tween 20, ionic: SDS). Doping of uncharged surfactant micelles with ionic surfactants can be used for a very precise control of the micellar charge and therefore the intermicellar interactions. By using SANS we want to determine the micelles bulk nanostructure (i.e. the micellar shape (extracted from P(Q)) as well as their interactions(extracted from S(Q))). This understanding will act as the basis for the descirption of the interactions of two solid surfaces throughout micellar dispersions. Those interactions are often determined by the dispersions nanostructure, the so called 'structural forces'.
