Reversible Addition-Fragmentation Chain Transfer Polymerization from Surfaces

Reversible addition-fragmentation chain transfer (RAFT) polymerizationbased surface modification has emerged as a powerful tool for preparation of well-defined polymers grafted solid substrates. Combination of the RAFT process with highly efficient ligation reactions involving click chemistry can further extend its application in controlled synthesis of functional hybrid and composite materials. This review highlights some basic features of this method and describes synthesis of polymer-grafted solid surfaces such as silica particles, metal oxide, gold nanoparticles, cellulose, and graphene oxide. Applications of such functional materials, including their use in functional additives, bioactive surfaces and biomaterials, stationary phases for chromatographic applications, and preparation of hollowcapsules and molecularly imprinted polymer films, are also summarized.
