Gluconic acid and hydrazine were respectively used as the complexing and reducing agents for nickel ions. The deposits were heat-treated. The microstructures and magnetic properties of the deposits were examined. The MWCNTs were homogeneously coated with pure nickel and their surfaces were relatively bumpy. These pure-nickel-coated MWCNTs exhibited ferromagnetism and had higher magnetizations and coercivities than electroless Ni-P alloy-coated MWCNTs. The bumpy morphology of the pure-nickel coating became relatively smooth on heat-treatment., Article, ELECTROCHEMICAL AND SOLID STATE LETTERS 13: D94-D96(2010)}, pages = {D94--D96}, title = {Pure-Nickel-Coated Multiwalled Carbon Nanotubes Prepared by Electroless Deposition}, volume = {13}, year = {2010} }
