The invention discloses a polyaniline modified boron nitride composite material and a preparation method and application thereof. The invention realizes the covalent connection of polyaniline and hexagonal boron nitride, and improves the corrosion resistance of the passive film through the synergistic effect of doped polyaniline and boron nitride: hydroxyl boron nitride is modified by aminobenzoic acid, so that the surface of the boron nitride has a graft site of polyaniline, PABA-BN is subjected to covalent modification by polyaniline, aniline is successfully polymerized on the surface of the PABA-BN, the dispersion performance of lamellar two-dimensional material hexagonal boron nitride in a passivator is improved, the agglomeration phenomenon is reduced, and the barrier shielding performance of a passivation film is improved. |
