▎ 摘　　要

NOVELTY - Preparation of covalently bonded polyaniline nanorod-graphene aerogel absorbing material involves preparing graphene oxide by modified Hummers method, reducing with hydroquinone by chemical reduction method, obtaining reduced graphene aerogel, introducing epoxy bond into amino group in pressure reactor by adding aqueous ammonia, obtaining amino functionalized graphene, initiating polymerization of aniline under condition of initiator and amino functionalized graphene, and covalently bonding polyaniline nanorod-graphene aerogel absorbing material. USE - Preparation of covalently bonded polyaniline nanorod-graphene aerogel absorbing material (claimed). ADVANTAGE - The method efficiently provides covalently bonded polyaniline nanorod-graphene aerogel absorbing material having increased orientation polarization and dielectric loss, and eliminates uneven electron cloud density on graphene aerogel surface and improves absorbing properties of the material.
