In-situ core-shell polymerization of magnetic polymer nanocomposite (PAAc/Fe3O4) particles via gamma radiation

Gamma radiation as a novel approach to synthesize core-shell magnetic polymer nanocomposite (PAAc/Fe3O4) particles was investigated. The Fe3O4 nanoparticles were primarily prepared by in situ precipitation–oxidation and radiation polymerization of polyacrylic acid PAAc. The polymerization process wa...
