| 摘 要： | 以超支化聚(胺-酯)为模板,采用NaBH4直接还原和紫外灯光照射合成了Ag纳米粒子。超支化聚(胺-酯)对Ag纳米粒子形成起着重要的作用。TEM分析表明,Ag纳米粒子形貌为球形结构,分布均匀,粒径约为45 nm(NaBH4还原)和20 nm(紫外灯光照射)。发现在UV-Vis谱图中420 nm左右有Ag纳米粒子特征表面等离子共振吸收峰。FT-IR分析发现Ag纳米粒子和超支化聚(胺-酯)之间有较强的相互作用,超支化聚(胺-酯)对Ag纳米粒子的稳定性起保护作用。

| Abstract: | Silver nanoparticles in hyperbranched poly(amine-ester)(HPAE) were prepared by means of NaBH4 reduction or UV irradiation.HPAE was found to play a key role in the formation of nanosized particles.Transmission electron microscopic(TEM) analysis showed that silver nanoparticles were spherical structure and homogeneously dispersed in HPAE with diameters of ～45 nm(NaBH4 reduction) or ～20 nm(UV irradiation).The absorption peaks due to the characteristic surface plasmon resonance of the obtained silver nanoparticles were observed at ～420 nm in the ultraviolet-visible(UV-Vis) absorption spectra.FT-IR spectra confirmed that there were strong interaction between silver nanoparticles and HPAE,showing HPAE had proved to provide very effective protection to the stability of silver nanoparticles. |
