Abstract
The present invention discloses s novel synthesis method of nickel fibers. The method of the present invention involves reducing nickel ions in an aqueous solution with a reducing agent in the presence of a base, a pH buffer, and a magnetic field or a surfactant at a temperature of 80-100° C. for a period of time, wherein a pH value of the aqueous solution is not less than 11.0 during the period of time, so that nickel fibers are formed in the aqueous solution. The nickel fibers synthesized in the present invention have a diameter ranging from sub-micron to microns, and a length up to centimeters.
