The application characteristics of metal nanoparticles can be effectively improved by loading them on the polymer aggregation surface equably and orderly through a simple and effective way, which is one of the hot research. This project designed and synthesized new kinds of polymeric carriers by changing the reaction conditions, to control its molecular weight and molecular weight distribution, and loaded metal nanoparticles on the media surface in mild conditions. New form of polymeric carriers were designed and selected in order to achieve an order distribution and array for metal nanoparticles. The content of the project include the research of interaction between nanoparticles and carriers, and the investigation of supported position, supported amount, directional distribution, size and crystal type on the surface of polymeric carriers, as well as the influences for preparation, morphology, surface constitutes, and the bulge distribution of polymeric carriers on loading metal nanoparticles. New spectral characteristics of the composite were explored and the polymer-metal nanoparticle system was applied in anti-bacterial, catalytic and other fields. The implementation of this project characterized various factors affecting morphology and composition of polymeric carrier, achieved an uniform and orderly arrangemen of metal nanoparticles on polymer medium, and endowed new features for spectroscopy and a higher catalytic activity with dispersed metal nanoparticles.
