| PEI/GO nanocomposites had been firstly prepared by green reduction method utilizing 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 reducing effect of amino-group on silver ion and the protection effect of silver nano particles. The influences of reaction time and concentration of silver ions on the prepared silver nanocomposites had been studied. The prepared AgNPs/PEI/GO complexes had been characterized using infrared spectroscopy, UV spectra, XRD, TEM, and other means. The characterization results showed that we had successfully prepared AgNPs/PEI/GO nanocomposites with good electric conductive properties using green and clean technology. |
