Soluble Nickel Plated Carbon Nanotubes
CNT / metal composite materials exhibit many unique properties, metal-coated carbon nanotubes is in maintaining the premise of the intrinsic properties of carbon nanotubes, increasing the surface active sites of carbon nanotubes to improve the resin between carbon nanotubes and weak interfacial bonding.
Nickel metal with high hardness, good toughness, ferromagnetism, excellent performance, and often as a second phase doping in other metals or non-metals. Therefore, the study of carbon nanotubes plated with nickel also aroused great interest the majority of researchers.
Since the non-metallic nanotubes belong, having no chemical catalytic activity, and the surface activation energy is high, is difficult to be wetted nickel, iron, cobalt and other metals or compounds, therefore, want to get good adhesion, uniform coating, must activation treatment of the carbon nanotubes, so as to have catalytic activity. Commonly used methods are sensitized activation - activation method, colloidal palladium activation method, and no palladium activation method. Ni itself is a very strong self-catalytic properties of metal, and thus the occurrence of strong self-catalytic activation area of carbon nanotubes, in the direction of grain growth in normal and tangential growth helps tangential surface of carbon nanotubes The non-activated area coverage Ni layer growth method to reflect the coating thickness direction of the growth rate, can be obtained as the reaction proceeds continuous, uniform coating surface of carbon nanotubes.
