| Abstract: | It is reported, for the first time, that compact nickel-multiwalled carbon nanotube (Ni/MWCNT) composites were successfully electrodeposited in choline chloride/urea based deep eutectic solvent (DES) on a copper substrate. Dispersion stability of MWCNTs is excellent in DES nickel chloride solution therefore electrodeposition of Ni/MWCNT composites was easily achieved. MWCNTs were uniformly distributed in the nickel matrix and gave different morphologies and high surface roughness to the coating. Coating with oxygen-functionalized MWCNTs exhibited higher stability and better corrosion resistance than the coating with pristine MWCNTs. |
