USE - The method is useful for graphene laminated composite doping method (claimed). DETAILED DESCRIPTION - Graphene laminated composite doping method comprises: (a) preparing an oxidant coating solution using an oxidant and an inert organic solvent, where the oxidant is iron p-toluenesulfonate with a dosage of 0.1-5 wt.%, and the inert solvent comprises ethanol, isopropanol, n-butanol, ethyl lactate, ethylene glycol monoethyl ether and/or ethylene glycol monobutyl ether; (b) coating the oxidant coating solution on the surface of target substrate, heating and drying to obtain oxidant coating having a thickness of 1-30 nm i.e. target substrate/oxidant coating composite structure; (c) placing the oxidant coating coated target substrate in a sealed container and heating to 50-130 degrees C; (d) carrying out heating gasification of conductive polymer precursor, mixing with a carrier gas and passing through the sealed container with a mixed gas flow rate of 10-100 sccm for 20-60 minutes for small molecules adsorption on oxidant precursor coating to form aggregate first doped coating, where the conductive polymer precursor comprises pyrrole and 3,4-ethylenedioxythiophene, the carrier gas is 80-99 vol.% of nitrogen or argon; (v) soaking the first doped coating in deionized water and then drying; and (vi) transferring graphene into first doped coating target substrate.
