Monte Carlo simulation is performed to study the adsorption properties of polymers on an attractive surface.Annealing method is adopted to simulate the adsorption characteristics and conformational changes of polymer chains driven by an external driving force F. In simulations using cooperative motion algorithm, the ensembles of monomers located at lattice sites are connected by non-breakable bonds. When the external force is F = 0, the finite-size scale method can be used to determine the critical adsorpti...
