Abstract

The invention discloses a preparation method of a network polyaniline conducting active material. The method comprises the following steps: dispersing 0.5mL of aniline in a beaker containing 50mL of deionized water by ultrasonic for 1 hour to obtain an aniline ultrasonic dispersion solution; weighing a certain amount of phytic acid, adding into the aniline ultrasonic dispersion solution, carrying out ultrasonic dispersion for 1 hour to obtain an aniline-phytic acid mixed solution, putting in an ice water bath, and cooling the aniline-phytic acid mixed solution to 0-5 DEG C; weighing ammonium persulfate and 5mL of 1mol / L hydrochloric acid solution, adding into a beaker containing 50mL of deionized water, and uniformly mixing to obtain a mixed solution; and dropwisely adding the mixed solution into the aniline-phytic acid mixed solution, carrying out polymerization reaction for 6 hours, carrying out vacuum filtration and washing with deionized water until the filtrate is neutral, putting the filter cake in a 50-DEG C vacuum drying oven, drying for 24 hours, grinding, and collecting to obtain the network polyaniline conducting active material.
