The invention relates to a preparation method of a sulfonated CNT loaded polyaniline nanorod super capacitor electrode material, comprising the following steps of: (1) ultrasonically processing a CNT and subjecting the CNT to diazotization reaction with diazosalt of sulfanilic acid so as to obtain a water soluble sulfonated CNT; (2) carrying out a chemical oxidation polymerization method to prepare a sulfonated CNT loaded polyaniline nanorod conductive composite material by employing the water soluble sulfonated CNT as a carrier, selecting the protonic acid with large-size acid radical ions as a reaction medium, employing the aniline as a reaction monomer, employing the ammonium persulfate as an oxidant and controlling the mole ratio of the ammonium persulfate to the aniline monomer to be less than 2; and (3) performing oxidation post-processing to the composite material by adopting the oxidant so as to prepare the sulfonated CNT loaded polyaniline nanorod super capacitor electrode material.
