Abstract
By introducing a head‐group energy of adsorption with the grafting surface, we simulate the grafted polymer layer including chain exchange with the bulk solution using the bond‐fluctuation model. The kinetics of adsorption is relatively rapid in short times and becomes much slower in later time as the layer is formed. The self‐adjusted surface coverage is measured for different values of chain lengths and head‐group energies. We also found that the polymer chains in a grafted layer are replaced by introducing shorter chains of identical head groups, which is also observed in recent experiments.
