This study investigates the adsorption of linear polymers onto wave like surfaces using Monte Carlo simulations on 2D lattice. Using the bond fluctuation model (BFM), we analyzed the behavior of polymer chains of length (N) near a surface. We computed the mean-square end-to-end distance ‹R2› and mean-square radius of gyration ‹Rg2› for polymer by varying chains lengths (N). Interestingly, the scaling behavior of these properties with chain length deviates from the expected universal relationships due to the wave like surfaces. The number of adsorbed monomers, the fraction of adsorbed monomers, and the adsorption energy were determined for polymer chains of different lengths on a corrugated surface. The influence of interaction strength on adsorption energy was also investigated. Our findings indicate that the longest chains exhibit the highest surface coverage of adsorbed monomers. Shorter chains, however, display the maximum average adsorbed monomer fraction and optimal surface coverage. The factors affecting polymer adsorption onto surfaces include the strength of polymer-surface interactions, surface properties, length of the polymer chains, and the adsorption energy. For adsorption to occur, the energetic benefit gained from binding to the surface must exceed the loss in conformational freedom of the polymer chain. The influence of surface topography on polymer adsorption has been extensively studied using wave-like surfaces as a model system. Molecular simulations have been used to explore the effects of these surfaces on polymer behavior.
