The Monte Carlo simulation method was used to simulate the adsorption of random copolymers on the solid/liquid interface. The microstructure information of adsorbed layer, such as adsorbed segment profile and distribution of sizes of various adsorption configurations, and the macrostructure information, such as total segment and segment density profiles, bound fraction, surface coverage, adsorption amount and adsorption layer thickness were obtained. In this work, the effect of attractive segment content f and its energy was investigated. It was shown that there were mostly smaller trains and smaller loops near the interface, but the distribution of loops configuration was wider. Small loops increased rapidly with increasing attractive segment content, and the distribution of train configuration became wider. As f and adsorption energy increased, bound fraction, surface coverage and adsorption amount also increased, but the thickness of adsorbed layer decreased.
