▎ 摘　　要

NOVELTY - A modified phenolic resin is prepared by uniformly stirring phenolic compound, aldehyde compound and acid catalyst, reacting to prepare phenolic resin intermediate, adjusting pH to 6.0-8.0, adding acetic acid or amino polycarboxylic acid and transition metal salt, reacting to prepare aqueous modified phenolic resin, heating at 0.085-0.1 MPa, and adding ethanol or ethylene glycol to adjust viscosity. USE - Method for preparing modified phenolic resin used for in-situ generating graphene (claimed). ADVANTAGE - The method is simple, has mild operation condition and high resin yield, and does not introduce impurities. The resin has graphene yield reaching 0.1-10 wt.%.
