本文利用高分子聚合物PEI链上富含氨基这一特性,绿色还原制备了PEI/GO纳米复合材料,然后利用未反应的氨基对银离子的还原作用和银纳米粒子的保护作用,将银纳米粒子固载到PEI/GO纳米复合物表面,制备了AgNPs/PEI/GO复合物。我们研究了反应时间和银离子浓度对所制备的银纳米复合材料的影响,并利用红外光谱、紫外光谱、XRD、TEM等手段对所制备的AgNPs/PEI/GO复合物进行了表征,表征结果显示我们成功的利用绿色环保的方法制备了具良好导电性质的AgNPs/PEI/GO纳米复合物。

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.
要光明正大,不要搞阴谋诡计!
