Anodization of aluminum and dying with Infrared absorbing materials

点击翻译按钮获取中文摘要

Inorganic acids will be used to anodize the aluminum pieces. The anodized aluminum pieces will be processedindividually by two different methods. The first method will involve dyeing using organic pigments to obtainblack colours. An aqueous solution of cyanine will be used as IR absorbing organic dye. The second methodwill involve the use of inorganic materials, namely, vanadium oxide (VO2) as well as cobalt sulphide (CoS) toobtain black coating on the anodized surface. These dyes/coatings incorporated anodized aluminum will beused as customized pieces for our specific industrial partners who are specialized in the fabrication of opticaldevices such as body parts of the cameras used on the surface of the earth or in the spacecrafts.
