Atom transfer radical polymerization (ATRP) has been developed rapidly since the first example of ATRP reported by Matyjaszewski's and Sawamoto's groups, respectively, in 1995. In view of the intrinsic toxicity of the copper compound, iron salts are particularly attractive for using as the ATRP catalyst due to its good biocompatibility and low toxicity. Herein, a series of different iron-mediated ATRP systems including normal ATRP, reverse ATRP, initiators for continuous activator regeneration for ATRP (ICAR ATRP) and activators generated by electron transfer for ATRP (AGET ATRP) were developed by our group, and the polymerization kinetics was studied in detail. In addition, the iron-mediated AGET ATRP was also successfully applied to the surface modification of different substrates such as chitosan, silica and magnetic nanoparticles to obtain functional materials.
