The invention relates to a preparation method for polypyrrole/polythiophene derivative compound conductive high polymer material, which comprises the following steps: firstly, boron trifluoride diethyl ether and aether are blended, and then added with ionic liquid to obtain A solution; pyrrole and thiofuran derivative monomer are added into the A solution to prepare B solution; the B solution is added into an electrolytic cell equipped with three electrodes; and electrochemical polymerization is carried out under the protection of nitrogen; polymerized current density is 1-10 mA/cm2; a layer of uniform polypyrrole/polythiophene derivative complex film can be obtained on a working electrode after polymerization is finished; the working electrode is taken out for washing and dried in the temperature of 60 DEG C. The preparation method has the beneficial effects that the composite electrode material prepared by the invention has about 200 F/g of bulking value and an electrical potential widow with about 0-2.8 wi
