| Abstract: | Monte Carlo simulation method is used to study the adsorption of AB diblock copolymers in a selective solvent at the solid-liquid interface. The adsorption isotherm and the quantities which manifest the microstructure of the adsorption layer, such as thickness of adsorption layer, bound fraction of adsorbed chains, surface coverage, segment concentration profile, etc., are obtained. The adsorption configuration size and distribution which indicate the configuration of adsorbed polymer are also obtained. The effects of repulsive interaction energy between solvent molecule or segment B and segment A, the content of segment A in AB diblock copolymer and bulk concentration on the various adsorption properties are studied. |
