Metalcontaining nano-particles within polymeric matrices: preparation, structure, and properties

A universal method of introduction of metal-containing nano-particles in polymeric matrices has been developed, which allows for the fabricating of large amounts (kilogram-scale) of polymeric nanoparticles composites. The encapsulation was done by thermal decomposition of metalcontaining compounds (MRn; M = Cr, Mo, W, Ti, Zr, Fe, Co, Ni, Pd, Pt, Cu; R = CO, HCOO, CH3COO, C6H5CH2) in solution melt of polymer (polyethylene, polypropylene, polytetrafluoroethylene, polyamide, polyarylate, polycarbonate, polysterene, polyethers, polyphenyleneoxide, siloxane). Particle size measurement (2-10 nm) and magnetic properties showed that the material really contained the nanoparticles, which were retaining their unique properties. (C) 2002 Elsevier Science B.V.
