Brush regime collapsed

In a solvent that selectively solubilizes one of the blocks, when the chain adsorbs, the anchor collapses to form a dense layer, while the buoy stretches out to form a brush-like structure. Adsorption in this case is decided by the competition between van der Waals attraction between the anchor and the substrate and repulsive interactions between the buoys. This is referred to as the van der Waals brush regime (37).
