▎ 摘　　要

NOVELTY - Preparing porous graphene/Ti3C2Tx composite thin film material comprises adding porous reduced graphene oxide with excellent water dispersibility into the Ti3C2Tx to obtain a mixed solution, vacuum filtering and dissolving filter membrane in organic solvent. USE - Method for preparing porous graphene/titanium carbide composite film material for ultra-fast electrochemical capacitor used as new alternating current (AC) line filter device. ADVANTAGE - The composite material of specific micro-structure, directly treated a certain process to obtain without adhesive, agent, ultra-thin film electrode, assembled into electrochemical capacitor, with outstanding filtering performance, and it has low cost and high characteristics.
