摘要：

Dispersion of magnetic γ-Fe2O3 particles which have an adsorbed epoxy-resin layer is investigated. γ-Fe2O3 particles which have various amounts of adsorbed polymer are prepared, and some parameters, which characterize the adsorbed layer, are measured. When the amount of adsorbed polymer increases, the thickness of the adsorbed layer also increases, but the polymer concentration of the adsorbed layer is kept constant in accordance with the polymer/solvent solubility. It is found that a low sedimentation rate, i.e., good dispersion stability, is caused by large amounts of the adsorbed polymer. © 1990.
