Polymer-metal Nanocomposites with Catalytically Active and Biocide Nanoparticles

The technology for production of nanocomposites for different applications has been extensively modifided in the last decade. The development of polymer-stabilized metal nanoparticles (NPs) is considered to be one of the most promising solutions to the stability of NPs. The incorporation of magnetic nanoparticles into polymeric matrices can impart unique properties in polymer composites. In this respect, the intermatrix synthesis and application of various polymer-metal nanocomposites were investigated. By this method it was possible to load magnetic nanoparticles into polymer matrix. The novel strategy for intermatrix synthesis was based on super paramagnetic core coating with a functional shell that could impart bactericide and catalytic properties in nanocomposites. The established magnetic nanoparticles with functional polymers were able to bind to metal ions. Reducing agents were used to produce metal nanoparticles which influenced the size and their distribution in polymer matrix. These polymer-stabilized metal nanoparticles prevented their self-aggregation and reduced their emission into the environment. The polymer-metal nanocomposites is suitable for catalytic and water treatment applications.
