Scattering method for surface covalent modification modification of nickel nanowires

The invention discloses a scattering method for surface covalent modification modification of nickel nanowires. The scattering method includes the following steps that (1) a nickel nanowire surface treatment solution and a modification agent are prepared; (2) the nickel nanowires are added to the surface treatment solution, and after the stirring at constant temperature, the nickel nanowires are flushed repeatedly with deionized water till being neutral and are subjected to vacuum drying; (3) the treated nickel nanowires are added to the modification agent, and after the stirring at constant temperature, the nickel nanowires are flushed repeatedly with deionized water and an ethanol solution and are subjected to vacuum drying; and (4) the multiple prepared modified nickel nanowires are added to an aqueous solution through weighing, and after the mixture is stirred at an even speed, a nickel nanowire aqueous solution is obtained. Compared with the prior art, the scattering method solves the problem that the nickel nanowires are prone to aggregation or winding in the aqueous solution, the nickel nanowires are fully scattered in the aqueous solution with a low cost, and the scattering method is easy to implement, low in cost and high in efficiency and has broad application prospects.
