摘　　要：探索通过溶胶-凝胶法制备太阳光谱选择性吸收涂层的主要思路及方法。本文以硝酸镍、异丙醇铝作为主要原料,通过溶胶-凝胶法制备出了Ni-Al2O3前驱体溶液,并通过提拉镀膜,在600℃氮气气氛下热处理得到Ni-Al2O3太阳光谱选择性吸收涂层。并对涂层的组成、微观形貌和光学性能进行研究,该涂层具有较好的形貌结构以及优异的光学性能。Explore the main ideas and methods for the preparation of solar selective absorber coating.In this paper,we used nickel nitrate and aluminum isopropoxide as the main raw material,and prepared the Ni-Al2 O3 precursor solution by Sol-Gel method,and then the Ni-Al2 O3 solar selective absorber coating was obtained by heat treatment at 600℃in nitrogen atmosphere after dipping-coating.We study the composition,microstructure and optical properties of the coating and find that the Ni-Al2 O3 coating has good morphology and excellent optical properties.
