▎ 摘　　要

NOVELTY - A precursor solution comprising phenolic precursor and graphene oxide is prepared and heated, to obtain phenolic system micro sol with viscosity of 20-40 mPa.second. The phenolic system micro sol is coated, to obtain micro sol film. The micro-sol film is subjected to sol-gel reaction, solvent replacement and supercritical drying, to obtain phenolic aerogel. The phenolic aerogel is carbonized, to obtain carbon aerogel thin film. USE - Preparation of carbon aerogel thin film (claimed). ADVANTAGE - The method enables preparation of carbon aerogel thin film with excellent mechanical property.
