Carbon nano-coils coated with nickel and gold by using electroless plating process

This paper presents the Carbon Nano-coils (CNCs) which were coated with nickel (Ni) and gold (Au) using electro-less plating method. The property of products was observed by Scanning Electron Microscope (SEM) and Energy Dispersive Spectrometer (EDS) and X-ray diffraction (XRD) and Fourier transformed infrared spectroscopy (FTIR), which shows formation of oxygen containing groups such as OH and COOH. We modified the CNCs by using acid wash and electro-less plating, and tested their magnetic property. The nickel film was deposited on the surface of the CNCs by electro-less plating for 10 mins at PH 7.0, and bath-temperature was 70°C. And we found the CNCs with surface coated by high ratio of Ni were attracted by the external magnetic field. The thickness of the deposit and the deposition rate may be controlled through careful variation of the coating time and plating bath temperature.
