Abstract: The surface initiated polymerizations with different polymerization rate and different ratio of the transformation (activation/deactivation) probability under high grafting density are investigated using molecular dynamics simulation method. We find that polymerization rate and the ratio of activation/deactivation process greatly determine the properties of polymer brushes. By modifying the polymerization rate and tuning activation/deactivation process, we can obtain the polymer brushes with low polydispersity index in relatively short time.

Key words: surface initiated polymerization, activation/deactivation, polymer brushes
