【摘要】 近年来,中高温太阳光谱选择性吸收涂层（以下简称为中高温吸收涂层）的研制及其在工业上的应用成为人们日益关注的焦点。本文在分类总结中高温吸收涂层的基本类型、作用机理和制备方法的同时,介绍了国内外不少科研工作者的的研究工作和最新成果,并对中高温吸收涂层的制备方法优缺点及其发展方向进行了探讨。本课题以黄铜（紫铜）片为基材,采用水溶液化学法,分别制备出CuO和PbS吸收涂层,并研究了最佳的制备条件,初步探讨了这些影响因素对太阳光谱选择性涂层的吸收率的作用大小。产品的主要性能通过耐温性、耐腐蚀性、耐磨性等各种测试进行表征,经测试表明,基本达到所要求的标准。本课题的创新性在于（1）制备CuO时,首次用次氯酸钠作为氧化剂,简便易行,无污染;（2）制备PbS时,直接在抛光后的黄铜上面镀膜,而不是像通常文献中的先镀镍后镀PbS,而且我们尝试在吸收层PbS上再涂覆TiO₂ ,以延长涂层的寿命。更多还原

【Abstract】 In recent years, the research and application in the industry of solar spectrallyselective absorbing coatings for medium & high-temperature applications（hereinafter briefly called ACMHA）have been given more and more attention. Thisthesis summarized their basic types, absorption mechanisms and preparation methodsand introduced the research work and new results of many scientific groups at homeand abroad. Furthermore, this thesis discussed the advantages and disadvantages ofpreparation methods for ACMHA as well as its development direction.We have prepared CuO and PbS selectively absorbing coatings by adoptingthe aque-chemical method with the base material of brass（or copper ）, studied theoptimal preparation condition, and discussed primarily the effects the related factorshave on the coatings. The major performance of the samples has been characterizedby adopting temperature test, corrosion endurance test, abrasion resistance test, etc,and the results shows that the samples have basicly reached our criterion.The creativity of the thesis lies in : （1） the oxidant of NaClO was fistly usedto prepare CuO selectively absorbing coating, and the preparation process was easy tohandle and without pollution;（2） not like the method of plating PbS on thenickle-plated brass（or copper） in the conventional literature, we plated PbS directly onthe pre-treated brass（or copper）, furthermore, we tried to paint TiO₂ on the PbScoating to prolong the coating life.更多还原
