Abstract: Computer simulation is carried out for end-grafted diblock copolymer chain AnBn by Monte Carlo method in this paper. Monomer A-surface interaction is EAS = ?1 and monomer B-surface interaction is EBS = 0. The adsorption and conformation properties of diblock copolymer are simulated by self-avoiding walk (SAW) and bond fluctuation model (BFM). The mean number of surface contacts, mean square end-to-end distance and mean square radius of gyration are studied and analyzed. We find that there are differences between two end-grafted diblock copolymers AnBn which end is grafted to the plate surface.

 

Keywords: Computer simulation, Monte Carlo method, Diblock copolymer, Self-avoidance.
