| 摘 要： | 采用共振散射光谱、紫外-可见吸收光谱、透射电镜对聚乙二醇(PEG)-Au3+纳米光化学反应进行了研究。讨论了金纳米粒子合成条件的影响，发现金纳米粒子的尺寸与PEG分子量大小有关。建立了一个利用不同分子量PEG制备一系列粒径为6～60 nm金纳米粒子的光化学合成新方法。根据PEG分子的空间位阻、疏水性等解释了PEG分子量不同而获得不同粒径金纳米粒子的原因。提出了一个合理的纳米光化学反应机理。 |

| Abstract: | The nano-photochemical reaction of polyethyelene glycol(PEG)-Au~(3+) was studied by resonance scattering and absorption spectrophotometry,and transmission electron microscopy.Influence of various factors on the preparation of gold nanoparticles was(considered.) There is a correlation between the molecular mass of PEG and the size of gold nanoparticles.A new photochemical method was proposed for the preparation of gold nanoparticles in size of 6-60 nm,using different molecular mass of PEG.The cause of obtaining gold nanoparticle with different size is the different space effect and hydrophobic property of PEG.A reasonable nano-reaction mechanism was developed. |
| Keywords: | Photochemical reaction Gold nanoparticles Polyethyelene glycol Resonance scattering |
