Monte Carlo Simulations of Adsorption of Diblock Copolymers at Solid-liquid Interface(Ⅰ)——The Configuration Distribution of Adsorbed Chains

Abstract

Abstract: Monte Carlo simulation method was used to simulate the adsorption of diblock copolymers at solid-liquid interface. The microstructure information of adsorbed layer, such as adsorbed segment profile and the distribution of size of various adsorption configurations, was obtained. In this work, the effect of attractive segment content and its adsorption energy on the adsorbed segment profile and distribution of size of configuration have been inspected. It is shown that the adsorbed layer thickness is mainly determined by the length of non-attractive segment.

Key words: Diblock copolymers, Adsorption, Monte Carlo simulation, Lattice model, Solid-liquid interface
