【摘要】 报导了在O/W,W/O,W/O/W以及LC这些有序分子集合体中制备Ag胶体的研究成果.利用W/O/W和LC可实现用高浓度AgNO3与N2H4·H2O反应制备出10nm以下的稳定Ag粒及Ag胶体.采用紫外可见、X射线衍射、电子显微技术对胶体及银粒进行了表征.发现团簇Ag外有层状结构.通过分析指出,层状结构体现了表面活性剂、助表面活性剂的有序双分子包复.更多还原

【Abstract】 Synthesis works on Ag clusters in ordered phase of O/W, W/O and LC are reported. Stabilized Ag particles and gel can be synthesized from high concentration of AgNO3 reduced by N2H4·H2O applying W/O/W or LC. The gel and particles were characterized by UV visible spectrum, X ray diffraction and transparent electron microscopy. We found the layer structure surrounding Ag clusters which illustrateds the double layer ordered phase coatings of surfactant and auxosurfactant.更多还原
