Research on Educational Reform of Versatile Diblock Copolymers Confined on the Face Centered Cubic Crystal

With the deepening of educational reform, the mechanism is explained from the molecular level, and the knowledge of mechanical science at the forefront of scientific research is integrated into classroom teaching. In this paper, Molecular Dynamic simulations was used to study the process of polymer brushes formed by the attached of polymer chains on polymer surface. The surface adsorption densities were distinguished according to different chain structures and counter ions. Two different modes are considered: (a) various the A-block lengths at fixed the chain length; (b) various the chain lengths at fixed the A-block length. The surface adsorption potential energy plays an important role in the shape of the diblock copolymer chain and the formation of the brush. The adsorption density studied in this paper can provide a basis for experimenters to design polymer brushes with required properties.
