A Simulation of Adsorption of Ampholytic Diblock Copolymers Confined in the Metal Crystal

Abstract

The diblock copolymer chain was flexible in the simulation system. The copolymer chain adsorption on the face center cubic metal crystal surface was researched by MD simulation. The adsorption density has been distinguished by the ratio of A-block beads to B-block beads. The counterions were added to the system which carry the opposite charges to B-block beads. The results show that the strongly binding between B-block and counterions, formed clusters. The copolymer is adsorbed on the bottom surface, which formed a copolymer brush.
