NANOSIZE METAL-CLUSTERS IN POLYMER SYSTEMS

Three synthetic methods have been developed for embedding nanosize met al clusters into polymers: (i) in situ synthesis of silver nanoparticl es in cross-linked poly-acrylamide gels, (ii) implantation of cryochem ically produced silver nanoparticles into poly-acrylamide gels, and (i ii) encapsulation of metal nanoparticles in poly-p-xylylene films. All methods allow one to produce 3-20 nm stable metal clusters embedded i nto bulk materials, thin films or fine particles dispersed in organic solvents or water. Results on some physical properties of the metal-po lymer systems thus obtained are presented.
