WebAn initiation reaction must occur to functionalize a monomer unit before the reaction can begin. Once a monomer has been functionalized, another monomer unit can bind to it, and the functionalized carbon center propagates to the new monomer unit. In this fashion, monomer units continue to attach to the polymer chain until termination occurs. WebIn this article, the coarse-grained molecular dynamics simulation combined with the stochastic polymerization model was applied to study the preparation of polymer chain-grafted carbon nanotube (CNT) via the “grafting-from” strategy.
