摘要：

The purpose of this study is to investigate the effect of sodium dodecyl sulphate (SDS) concentration on the surface morphology as well as infrared emissivity of porous Ni film prepared through the method of dynamic hydrogen bubble template (DHBT). The results indicate that the addition of SDS can enhance the hydrogen evolution reaction and increase the volume of evolving hydrogen bubbles during electrodeposition process, resulting in the increase of pore density, depth and diameter of Ni film. These factors affect the roughness greatly and the relationship between roughness and infrared emissivity has been inferred. A wide range of infrared emissivity (0.36-0.80) of porous Ni film was obtained through control of the concentration of SDS. It is concluded that the addition of SDS has a significant effect on the improvement of roughness of the porous Ni film and is beneficial for the film to obtaining high thermal emission.
