▎ 摘　　要

NOVELTY - Preparing nanocomposite material comprises making the ethanol as the medium, making the p-toluene sulfonic acid as the surface active agent, making the polyethylene glycol - 400 as the phase transfer catalyst, and making the iron (III) chloride hexahydrate as the initiator; and polymerizing the pyrrole in-situ on the graphene on the ultrasound condition to obtain the nanocomposite material. USE - Method for preparing nanocomposite material (claimed) used in sensor, electronic element and biomedicine. ADVANTAGE - The method can provide composite material having good thermal stability, conductive performance and processing performance.
