実験手順

First, a magnetic structure 2 having a coating layer 16 on the surface thereof is prepared. Magnetite particles are heated under a dry N2 atmosphere and are then dispersed in anhydrous toluene. To this magnetite particle/toluene dispersion liquid, 2-(4-chloromethylphenyl)ethyltrimethoxysilane as a silane-coupling agent is added for introducing a chloromethyl group to the magnetite particles. This reaction can be confirmed by detecting Cl atoms by XPS. The magnetite particles to which chloromethyl group is introduced are dispersed in water. Sodium dithiocarbamate is added thereto for the reaction with the chloromethyl group. Thus, an initiating point for UV graft polymerization is introduced to the surfaces of the magnetite particles. This reaction can be confirmed by detecting N atoms and S atoms by XPS. Then, the magnetite particles and acetone are weighed into a reaction vessel and the magnetite particles are dispersed in the acetone by sonication. Then, glycydil methacrylate is weighed into the reaction vessel, and the reaction vessel is purged with nitrogen. Then, UV graft polymerization is performed with UV light of a wavelength of 312 to 577 nm irradiated by a UV lamp at room temperature for 2 hr to form polyglycidyl methacrylate on the surfaces of the magnetite particles. This reaction can be confirmed by an increase in the particle diameters measured by a dynamic light scattering method.
