Abstract: Methods are disclosed for synthesizing nanocomposite materials including ferromagnetic nanoparticles with polymer shells formed by controlled surface polymerization. The polymer shells prevent the nanoparticles from forming agglomerates and preserve the size dispersion of the nanoparticles.
