Abstract

Hybrid magnetic composites made up of calibrated maghemite nanoparticles well dispersed in an epoxide resin were obtained by polymerization of the resin inside stable organosols of maghemite. The sol stability was ensured by ligand adsorption onto the particle surface. Studies of phenylphosphonic acid adsorption are presented. They show a strong interaction between PPA ions and hydroxyl groups of particle surface and through bridging ≡Fe2O2POΦ species. Infrared and Mössbauer spectroscopies as well as quasi- elastic light scattering and transmission electron microscopy were used to characterize the materials.
