▎ 摘　　要

NOVELTY - Preparing polybenzoxazine-based graphene involves using a phenol source, an amine source and paraformaldehyde or formaldehyde as raw materials to synthesize benzoxazine monomer and/or oligomer, then heating, curing and crosslinking to obtain polybenzoxazine resin, and finally carrying out laser induction. USE - The method is useful for preparing polybenzoxazine-based graphene, which is useful in optoelectronic devices, electrochemical devices and sensors. ADVANTAGE - The method prepares the polybenzoxazine-based graphene with excellent electrochemical property and conductivity, high proportion of single layer and large specific surface area. The polybenzoxazine-based graphene promotes the development of carbon sources for the preparation of graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the polybenzoxazine-based graphene prepared by the above method.
