摘要: 报告了一种利用Gibbs膜反应制备颗粒膜的技术.在制备CuS颗粒膜过程中,出现了棒状CuS纳米晶体的奇异现象.用透射电镜(TEM)、电子衍射(ED)和能量色散谱(EDS)等实验手段对所得CuS颗粒膜和棒状CuS纳米晶进行了分析和表征,并对棒状CuS纳米晶的形成机理进行了初步探讨.

关键词: 棒状CuS纳米晶, CuS颗粒膜, 液-液界面Gibbs膜反应技术

Abstract: A simple method to form particulate film under Gibbs film was reported. The CuS particulate film was synthesized, and a novel phenomenon of the formation of rod-like CuS nano-crystals at the oil-water interface was observed. The CuS particulate film was characterized by transmission electron microscopy and electron diffraction. Energy dispersive spectroscopy was employed to confirm the formation of the rod-like CuS nano-crystals.

Key words: CuS particulate film, rod-like CuS nano-particles, liquid-liquid interface Gibbs film
