▎ 摘　　要

NOVELTY - An electromagnetic wave graphene and polyaniline nanocomposite material is prepared by mixing graphene (0.015 g) and hydrochloric acid solution (100 ml), subjecting solution to ultrasonic dispersion at 5 degrees C, adding benzene amine (0.1-0.4 ml) and ammonium sulfate (0.125-0.5 g), cooling to 5 degrees C, stirring, adding ethanol, setting aside for 24 hours, filtering, washing filter cake with deionized water, and vacuum drying at 40 degrees C. USE - A graphene and polyaniline nanocomposite material for high-frequency electromagnetic wave absorbing coating (claimed). ADVANTAGE - The composite material has simple preparation, and can be applied to industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a high-frequency electromagnetic wave absorbing coating prepared by mixing graphene and polyaniline nanocomposite material with paraffin.
