Conductive polyaniline carbon nanotube core-shell hybrid composites, preparation methods and applications belong to the production technology field of nano antistatic and anticorrosive coatings. Carbon nanotubes (CNTs), aniline, dispersant and water were mixed to form a dispersion system. Organic acid was added into the dispersion system, and ammonium persulfate solution was dripped after stirring. After the reaction was finished, the solid phase was filtered, washed with ethanol and deionized water respectively, and then vacuum dried. After grinding and sieving, conductive polyaniline CNTs core-shell hybrid composites were obtained. The composite material is easy to disperse in oily or waterborne epoxy resin, and is easy to mix with coating base material. The coating used for coating can form a uniform and lasting conductive network. Compared with the mechanical properties without hybrid nanomaterials, the adhesion, toughness and impact properties of the composite material are significantly improved. Compared with other conductive electrostatic agents, the antiseptic performance of the composite material has unique passivation effect on the metal surface. The effect of electrochemical anticorrosion.
