Synthesis and Characterization of Silver Nanoparticles/Oxidation Graphene Nanocomposites by the Reduction Method
摘要
Abstract
Polyethyleneimine /graphene(PEI/GO) nanocomposites were prepared by the green reduction method and the feature that amino-groups are rich in PEI chain of the macromolecular polymer .Then, the AgNPs /PEI/GO complexes were prepared by immobilizing silver nanoparticles on the surface of PEI /GO nanocomposites utilizing the re-ducing effect of amino-group on silver ion and the protection effect of silver nanoparticles .The influences of reaction time and concentration of silver ions on the prepared silver nanocomposites were studied .The prepared AgNPs /PEI/GO complexes were characterized using infrared spectroscopy , UV spectra, XRD, TEM, and other means.The char-acterization results showed that PEI was successfully modified to GO surface , Ag + was reduced using green and clean technology and immobilized on GO surface .The AgNPs/PEI/GO nanocomposites have good electric conductive proper -ties and perfect crystal phase .关键词
