Van der Waals brush regime

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). 

A similar picture arises from a scaling analysis by Marques et al. [40]. The situation where there is a wetting layer of anchor blocks from which the brush blocks protrude is called the van der Waals brush regime. The central result states that the brush density is rather weakly dependent on chain...
