Summary:The invention discloses a cationized cellulose/graphene/polypyrrole conductive composite material and a preparation method and application thereof. The preparation method comprises the following steps: firstly, reducing graphene oxide by using a reducing agent to obtain reduced graphene oxide, taking bacterial cellulose as a matrix, modifying bacterial cellulose by using a quaternary ammonium salttype cationic etherifying agent to prepare cationized bacterial cellulose dispersion liquid, compounding the cationized cellulose dispersion liquid as a dispersing agent with reduced graphene to prepare cationized cellulose/graphene dispersion liquid, and finally, uniformly mixing the cationized cellulose/graphene dispersion liquid with a pyrrole monomer and an oxidizing agent thereby reacting toobtain the cationized cellulose/graphene/polypyrrole conductive composite material with excellent electrochemical performance. Unification of dispersity, system compatibility and electrochemical performance is achieved, the p
