Study of polyelectrolyte brushes and micelles

Abstract

In this present work we studied polyelectrolyte micelles and polyelectrolyte brushes by means of molecular dynamics simulations. These structures have been the subject of research for several years because of their importance. First of all, we studied polyelectrolyte micelles in salt-free solutions, which are formed from diblock copolymers with one charged and one solvophobic block. The research focuses on the effect of Bjerrun length, molecular weight and the degree of charge of the charged block in different properties. These properties are the aggregation number and the size of the formed micelles, the percentage of confined counterions contained in their corona and the zeta potential. Then we studied the movement of the micelles mentioned above in polyelectrolyte brushes.The brushes are formed by linear chains with opposite charge from the micelles, with varying grafting densities and charge content. The micelles perform a directed motion along the vertical z axis on the grafted su ...
