Abstract

In order to arrange directionally, multi-wall carbon nanotubes (MWCNTs) are functionalized with ferromagnetic cobalt on the surface via the electroless plating method. The uniform and continuous cobalt coating was received in pH = 9 at 45∘C for 30min. It is found that the hydroxyl and carbonyl groups could be successfully introduced on the surface of raw MWCNTs after treated in boiling nitric acid that would provide the active points for cobalt deposition. The diameters of the cobalt (Co)-coated MWCNTs increase to 20–50nm from 8–15nm of purified ones. As a result of nanoscale cobalt coating, MWCNTs show strong ferromagnetism at room temperature. The Co-coated MWCNT respond to magnetic field susceptibly in the distilled water and arrange themselves in the direction of the applied magnetic field up to 1T. The hysteresis curve results show that the coercivity of Co-MWCNTs is 1285.2 Oe, which is about four times that of cobalt powder itself.
