Influence of comb-shaped polymers architecture on interparticular forces

Bachelor Thesis

The aim of this thesis is to investigate the influence of the polymer architecture on inter-particle forces.

Therefore the interaction force between alumina surfaces across aqueous solutions containing comb shaped polymers are investigated via Colloidal-Probe Atomic Force Microscopy.
