Polyacrylamide-coated magnetic nanogels were synthesized ,via, photochemical polymerization under UV light irradiation. The polyacrylamide-coated magnetic nanogels were characterized by Fourier transform infrared spectroscopy and photo correlation spectroscopy. And it was found that particle size of the polyacrylamide-coated magnetic nanogels increased with the reaction time and the monomer concentration, but decreased with increasing concentration of the cross-linker of N, N,’,-Methylene-bis-(acrylamide). The coating mechanisms were studied by ESR measurements of different samples of the nanogels.
