采用电沉积技术在铜基上沉积了一层光亮的镍基纳米颗粒涂层，然后再进行喷涂。在没有光亮镍层的情况下，涂层的红外反射率在0.4左右，当镍层厚度为750 nm时，反射率增加到0.6。用黑色涂料和黑色涂料与光亮镍复合的太阳能集热器的效率比单独使用黑色涂料的效果要好。经过高温老化试验，光亮镍提高了吸波涂料的稳定性。商业涂料的集电极光学增益FR(Sa)降低了24.7%，与亮镍结合的商业涂料降低了19.3%。经过温度老化试验，商用涂料的总热损失FR(UL)增加了3.3%，与光亮镍复合的商用涂料增加了2.7%。(C)亚历山大大学工程系2016年。由爱思唯尔B.V.制作和托管。这是CC By-NC-ND许可证(http://creativecommons.org/licenses/by-nc-nd/4.0/).下的一篇开放获取文章
A nanoparticles layer of bright nickel base was deposited on copper substrates using electrodeposition technique before spraying the paint. IR reflectance of the paint was found to be around 0.4 without bright nickel layer and the reflectance increased to 0.6 at a Ni layer thickness of 750 nm. The efficiency of the constructed solar collectors using black paint and black paint combined with bright nickel was found to be better than black paint individually. After aging tests under high temperature, Bright nickel improved the stability of the absorber paint. The collector optical gain FR(sa) was lowered by 24.7% for the commercial paint and lowered by 19.3% for the commercial paint combined with bright nickel. The overall heat loss FR(UL) was increased by 3.3% for the commercial paint and increased by 2.7% for the commercial paint combined with bright nickel after the temperature aging test.
