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.
