The invention relates to a producing process of the electric polyniline nm particle. The spirit of salt of the aniline is electrolysed in the tri-pole system on the condition of existing high-magnetic field. When electrolyzing, the work electrode and the direction of the magnetic field keep vertically; then the outcome is the poly-aniline nm particle. The poly-aniline nm particle produced by the method is equal in size, inerratic in arrangement; so it can be used for the domain of the nm lead, the height ratio conductive polymer batteries, the electric catalytic reaction, the biosensor, the light emitting device, the electromagnetic screen. |
