Problems solved by technology

The technology of copper plating on ordinary materials is relatively mature, but for nanomaterials, the technology of electroless copper plating is more complicated and difficult to operate
[0003] In the prior art, there have been applications of carbon nanotubes coated with different metals, but their common characteristics are that the process route is long, the operation is complicated, and the precious metal palladium is used as the catalyst, so the cost is high and the industrialization is limited.

Abstract

The invention discloses a preparation method for plating copper on the surface of a carbon nano-tube, which is characterized by adopting Cu2+ as the source of the elementary substance copper and adopting Zn or HCHO as a reducing agent. When adopting Zn as the reducing agent, the main reagents are: CuSO4.5H2O, Zn powder, glycerol, glycol, potassium sodium tartrate, FeSO4.7H2O and HNO3. When adopting the HCHO as the reducing agent, the main reagents are: CuSO4.5H2O, HCHO, EDTANa2, FeCl3.7H2O, triethanolamine, a, a-bipyridine, NaOH and HNO3. The technological process of the plating copper on the surface of the carbon nano-tube is as follows: carbon nano-tube oxidation, water scrubbing, plating, water scrubbing and drying. The preparation method of the plating copper on the surface of the carbon nano-tube of the invention not only changes the traditional way of palladium catalysis but also has the advantages of low price and convenient operation, which simplifies process and is simple.
