Abstract 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.

十二烷基硫酸钠对多孔镍膜表面形貌和红外发射率的影响

摘要 本研究的目的是研究十二烷基硫酸钠（SDS）浓度对动态氢气泡模板（DHBT）法制备的多孔镍膜表面形貌和红外发射率的影响。结果表明，SDS的加入可以促进析氢反应，增加电沉积过程中析氢气泡的体积，从而增加Ni膜的孔密度、深度和直径。这些因素对粗糙度的影响很大，并且已经推断出粗糙度与红外发射率之间的关系。通过控制 SDS 的浓度，可以获得大范围的多孔 Ni 膜的红外发射率（0.36-0.80）。
