Abstract
A novel approach was developed to synthesize polymerizable vinyl group functionalized Fe3O4 nanoparticles with high aqueous dispersion stability. Firstly, the Fe3O4 nanoparticles were synthesized via chemical co-precipitation method. Then, azide-functional Fe3O4 nanoparticles were obtained by a two-step chemical modification process. Finally, a quaternized 2-(Dimethylamino) ethyl methacrylate (QDMA) with alkyne moiety were directly reacted with azide-functional Fe3O4 nanoparticles to obtain Fe3O4@QDMA nanoparticles. The Fe3O4@QDMA nanoparticles with a mean diameter 12.2 nm possess positive charges and can be well dispersed in water media for further preparation of particle-crosslinked magnetic nanocomposite hydrogels.
