中文摘要: 以溶液还原法对聚乙烯亚胺(PEI)和Cu2+形成的配合物进行还原，制备了金属Cu微粒。扫描电镜对微粒的分析表明，低浓度Cu2+配合物制备的微粒形态规则、分布均匀，粒径约0.98 μm。红外光谱、X-衍射对微粒组成的分析表明，PEI键合地包覆Cu微粒，没有Cu的其他氧化物存在，PEI包覆量占微粒质量的14.6%，形成的复合铜微粒体系有良好的稳定性。
Abstract:Copper microparticles were synthesized with solution phase reduction from a mixture of Cu2+ ions and poly(ethylene imine)(PEI). The prepared microparticles were observed by scanning electron microscope. Rresults showed that the particles, which were obtained by chemical reduction of low concentration complexes of Cu2+ and poly(ethylene imine), presented regular morphology and uniform distribution, and the average particle diameter was about 0.98 μm. FT-IR spectroscopy and X-ray diffraction measurements revealed that the PEI bonded to metallic Cu microparticles to form a coating layer, no other oxidation state of metal Cu were found. Mass fraction of the coated PEI in the particles was 14.6%. Furthermore, the solution system of the copper microparticles formed in the presence of PEI possessed a good stability.
