摘要：

The synthesis of well-dispersed composite Ni/NiO nanoparticles of controlled size has been achieved in organic solution in the presence of polyvinylpyrrolidone, using biscycloocta-1,5-diene nickel as a precursor, upon controlling the water and dioxygen content of the reacting medium. The particles are characterized by magnetisation measurements. Transmission Electron Microscopy and Wide Angle X-ray Scattering The oxidation of these particles into, NiO nanoparticles can be achieved in mild conditions and preserves their dispersion in the polymer matrix.
