Polyaniline-based composite material and preparation method thereof

The invention discloses a polyaniline-based composite material. The polyaniline-based composite material comprises the raw materials in parts by weight: 30-50 parts of aniline monomers, 8-15 parts of polyurethane resin, 100-200 parts of hydrochloric acid, 3-9 parts of carbon black, 1-6 parts of zinc oxide powder, 0.5-4 parts of polyvinylpyrrolidone, 10-30 parts of petroleum sodium sulfonate, 5-15 parts of atimony fluoride sulfonate, 4-16 parts of doctyl sulfosuccinate, 10-20 parts of hydrogen peroxide, 1-6 parts of iron powder, 4-17 parts of kaolin and 1-8 parts of lignin. The invention further discloses a preparation method of the polyaniline-based composite material. The polyaniline-based composite material prepared by virtue of the preparation method has good conductivity and bending strength, so that the application range of the composite material can be broadened; besides, the adopted process is simple and is relatively applicable to process production application.
