摘要
利用粗粒化分子动力学方法提出了一个包含活化/去活化可逆过程的表面引发聚合反应模型,用以研究高引发密度表面引发聚合反应过程中不同聚合速率和不同转化几率(活化/去活化)对产物聚合物刷性质的影响.可通过调节聚合反应几率和活化/去活化过程发生的比率,在相对短的时间内制备高引发密度下低分散性的聚合物刷.
The surface initiated polymerizations with different polymerization rate and different ratio of the transformation（activation/deactivation） probability under high grafting density were investigated using molecular dynamics simulation method.We present a simulation model of the surface initiated polymerization（SIP） by taking into account of the activation/deactivation process.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.
