Polymer Surfactant Interactions

Lucie Garreau (previous student, left the group in 2002)
In order to prevent the problem of re-deposition of soil particles onto clothes in the rinsing phase, companies have thought about modifying the surface of clothes and/or soil particles by polymer adsorption to increase repulsion forces. However, in the formulation of washing powders, polymers interact with surfactants. The aim of this project is therefore to understand Polymer-Particles-Surfactant interactions.
Techniques used: Photon Correlation Spectroscopy, Nuclear Magnetic Resonance, Small Angle Neutron Scattering, Surface Tension Measurements.
This project is funded by Unilever
