Optical and Structural Properties of Carbon Nanotubes/Black Nickel Composite Coatings by Electrodeposition

doi:10.15541/jim20160152

Abstract

Abstract:

Carbon nanotubes/black nickel composite coatings with high optical properties on titanium alloy substrate were prepared on the basis of composite electrochemical deposition methods. Micro scale morphology and optical properties of as-prepared materials were analyzed. The effects of carbon nanotubes concentration and electroplating current density on the optical properties were also explored. The results show that grain size of composite coating was small with microporous and increased surface roughness as compared with conventional black nickel coating. The absorptance (α_s) over a spectral range of 300-2300 nm was up to 98%, while the emittance (ε) over a 2.5 µm to 20 µm range was 94%, better than those of conventional black nickel coatings. The absorptance of composite coating increased firstly and then decreased with increase of carbon nanotubes concentration and electroplating current density.

Key words: carbon nanotube, electrodeposition, composite coating, solar absorptance
