Ultradense polymer brushes by adsorption.
Standing room only: Dense polymer brushes can be prepared by adsorbing a diblock copolymer comprising a neutral block and a polyelectrolyte block to an oppositely charged polyelectrolyte brush (see picture). The density of the resulting neutral brush is determined by charge compensation, leading to brush densities well over 1 nm(-2). The diblock copolymer can be desorbed by changing the solution conditions.
