化学池法制备二硫化钼膜 摘 要 二硫化钼是一种多用途的新型无机材料，它可以用作润滑剂添加剂、催化剂、涂层和密封材料。它广泛的适用于机械工业和汽车工业等多个行业。本文采用化学池法，以钼酸铵、氨水、连二亚硫酸钠、硫代乙酰胺为原料，在适当的条件下，在Si基底上镀一层镀层连续的二硫化钼膜。该方法具有工艺流程简单，反应条件温和等优点。本文旨在制备二硫化钼膜以及对化学池法制备二硫化钼膜方法的研究。通过X射线衍射(XRD)观察化学池法制备产物的波谱，以及通过扫描电子显微镜(SEM)照片观察产物形貌，研究镀层的状况。本文主要包括以下几个内容： 1.二硫化钼制备方法的总结，以及每种方法的优缺点。经多种方法比对提出化学池法制备二硫化钼膜的可行性。 2.总结了多种表征手段，说明了各种表征手段的基本原理。 3.做实验，得到镀在Si基底上的二硫化钼膜，通过X射线衍射观察二硫化钼的波谱，通过扫描电子显微镜照片对产物形貌进行观察。最后得出结论：化学池法制备得到的产物是二硫化钼，并且镀层紧致。说明化学池法制备二硫化钼是一种简单可行的方法。 关键词：二硫化钼，化学池法，表征，镀膜 PREPATED BY CHEMICAL BATH METHOD MOLYBDENUM DISULFIDE FILM ABSTRACT Molybdenum disulfide is a versatile new inorganic materials which can be used as lubricant additives, catalysts coating and sealing materials. It is widely applied in many industries such as machinery and automobile industries Cell by chemical methods, even with ammonium molybdenum, aqueous ammonia, sodium dithionite, thioacetamide as starting material, under suitable conditions, the Si substrate coated with a layer of molybdenum disulfide coating continuous film. This method has the process is simple, mild reaction conditions, and so on. This article aims to preparation of molybdenum disulfide film and prepared studies on the chemical tank molybdenum disulfide film method. Chemical pool equipment products observed by X-ray diffraction method (XRD) and scanning electron microscopy (SEM) photographs observed morphologies, research coating condition. This article includes the following content: 1. Molybdenum disulfide preparation methods, as well as the advantages and disadvantages of each method. Call for the possibility of Chemical cell method the through a variety of methods compare. 2. Summarizes a variety of characterization methods, explains the basic principles of a variety of characterization methods. 3. Experiment, get deposited on Si substrate molybdenum disulfide film, observed by X-ray diffraction spectra of molybdenum disulfide, by scanning electron micrograph on the morphology were observed. F
