Structure of a diblock copolymer adsorbed at the hydrophobic solid/aqueous interface: Effects of charge density on a weak polyelectrolyte brush

Abstract:

We have used neutron reflection to study the effects of pH and added electrolyte on the structure of a weak polyelectrolyte brush anchored by means of a hydrophobic block to a hydrophobic surface. The copolymer was poly(2-(dimethylamino)ethyl methacrylate-block-methyl methacrylate) (poly-(DMAEMA-b-MMA)) containing 70% DMAEMA and having a molecular weight of 10000. The MMA block and the hydrophobic octadecyltrichlorosilane (OTS) layer were deuterated in order to highlight the DMAEMA fraction o...
