We present our recent progress on the characterization of the equilibrium structural behavior of ferromagnetic supramolecular brushes. These systems consist of a polymer brush-like structure formed by grafted supramolecular ferromagnetic filaments instead of molecular polymers. In general, magnetic filaments are obtained by crosslinking magnetic colloids by means of macromolecules to form a permanent magnetoresponsive chain structure. The grafting of magnetic filaments on surfaces is a promising strategy to create field controllable coatings with many potential applications.
Our study is focused on the determination of the dependence of the brush structure on the interplay between the steric repulsions and the magnetic interactions of the colloids, and is based on extensive molecular simulations and analytical theories.
