The invention discloses a method for preparing graphene/carbon nano-tube/conductive high-polymer ternary composite materials. The method includes oxidizing multi-walled nano-tubes to obtain graphene oxide/carbon oxide nano-tubes; carrying out chemical oxidation-reduction reaction on the graphene oxide/carbon oxide nano-tubes and conductive high-polymer monomers (pyrrole, aniline, thiophene and the like); preparing the graphene/carbon nano-tube/conductive high-polymer ternary composite materials at one step under normal-temperature and normal-pressure conditions. The method has the advantages that expensive instruments and equipment can be omitted, procedures are simple and are easy to control, and the method is low in cost and easy to popularize; the graphene/carbon nano-tube/conductive high-polymer ternary composite materials prepared by the aid of the method have excellent potential application value in the aspects of energy storage, electrochemical sensing, electrochemical catalysis and micro-electronics.
