Monte Carlo simulations of adsorption of diblock copolymers an solid-liquid interface (I) - The segment concentration profile and adsorption amount

Monte Carlo simulation method was used to simulate the adsorption of diblock copolymers on solid-liquid interface. The adsorption information, such as total segment density and segment concentration profiles, bound fraction, surface coverage and adsorption amount, are obtained. The effect of attractive segment content f and its adsorption energy was inspected. It is shown that the adsorption amount increases with increasing f when adsorption energy is relatively small. However, if adsorption energy have a larger value, the adsorption amount increases with increasing fat first and reaches a maximum about f = 0.5, then decreases with increasing f. This trend coincides well with the experimental results of Tiberg et al..
