| 摘 要： | 在聚乙烯基吡咯烷酮(PVP)的存在下,微波辐射硝酸银水溶液,合成了纳米银/PVP复合物。UV-Vis和XRD结果证明了生成的纳米银具有面心立方结构,PVP中N原子对银离子具有催化还原作用。TEM结果表明纳米银粒径在10～25nm,且较均匀分散在聚合物基体中;XPS结果表明PVP与纳米银之间存在相互作用。

| Abstract: | Nano-silver/polyvinylpyrrolidone(PVP) composite materials were synthesized in the silver nitrate solution containing PVP by microwave. The mechanism of catalytic reduction of sliver ion by atom N in PVP was discussed. UV-Vis and XRD results indicate the presence of nano silver with face-centered cubic structure. TEM result shows that nano silver particles with 15~25 nm size were homogeneously dispersed in the PVP matrix. XPS results suggest that there is an interaction between PVP and nano Ag. |
