| 本文利用高分子聚合物PEI鏈上富含氨基這一特性，綠色還原制備了PEI/GO納米復合材料，然后利用未反應的氨基對銀離子的還原作用和銀納米粒子的保護作用，將銀納米粒子固載到PEI/GO納米復合物表面，制備了AgNPs/PEI/GO復合物。我們研究了反應時間和銀離子濃度對所制備的銀納米復合材料的影響，并利用紅外光譜、紫外光譜、XRD、TEM等手段對所制備的AgNPs/PEI/GO復合物進行了表征，表征結果顯示我們成功的利用綠色環(huán)保的方法制備了具良好導電性質(zhì)的AgNPs/PEI/GO納米復合物。 |

| 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. |
