Problems solved by technology

The preparation of carbon nanotubes / nano-nickel composite thin film materials by composite plating has made great progress, but there are still some problems. The difficulty of research is mainly due to the fact that carbon nanotubes are easily agglomerated in aqueous solution, resulting in rough surface of the coating. and inhomogeneity, limiting the reinforcing effect of carbon nanotubes in composites

Description

technical field [0001] The invention relates to a composite thin film material, in particular to a method for preparing a carbon nanotube / nano-nickel composite thin film material on the surface of a metal foil. Background technique [0002] The most typical application of nanomaterials is carbon nanotubes. Carbon nanotubes are seamless nanotube-like substances curled from single-layer or multi-layer graphite. Each layer of nanotubes is composed of a carbon atom that is completely bonded to the surrounding three carbon atoms through sp2 hybridization. The cylindrical surface composed of planes, due to its nearly perfect bonding structure, hinders the intervention of impurities and defects, making it have super strong mechanical properties and high chemical stability, and its chemical activity is lower than that of graphite. Carbon nanotubes are currently the thinnest fiber material due to their high length-to-diameter ratio (the diameter is within tens of nanometers, and the...
