NOVELTY - Preparing double-layer structure poly 3,4-ethylene dioxythiophene/graphene oxide-carbon nano-tube flexible transparent conductive film involves ultrasonically cleaning polyethylene glycol terephthalate (PET) substrate film by ethanol, drying, spraying mixed solution of graphene oxide (GO) and carbon nano-tube (CNT) on PET film substrate to form mixed layer of graphene oxide and carbon nano-tube (GO-CNT), processing with nitric acid (HNO3) at 10-12 megapascals (MPa), spraying poly 3,4-ethylene dioxythiophene (PEDOT) solution on surface of GO-CNT layer, diluting PEDOT solution to make it easier to spray, obtaining flexible conductive film with excellent conductivity by adding certain amount of ethylene glycol in PEDOT solution and using sulfuric acid (H2SO4) at 10-12 MPa after processing, preparing flexible conductive film of double-layer structure of GO-CNT mixed layer and PEDOT layer. USE - Poly(3,4-ethylenedioxythiophene)/graphene oxide-carbon nanotube flexible transparent conductive film with double-layer structure used for photoelectric device. ADVANTAGE - The poly(3,4-ethylenedioxythiophene)/graphene oxide-carbon nanotube flexible transparent conductive film has stable structure, high transmittance and low surface resistance. The graphene oxide, carbon nanotube and poly(3,4-ethylenedioxythiophene) are not simply stacked, but because the cross of each other forms a stable double-layer structure, with high adhesive force. The film preparation technique is simple, short period, high film conductivity, which can be widely applied to the photoelectric device. DETAILED DESCRIPTION - Preparing double-layer structure poly 3,4-ethylene dioxythiophene/graphene oxide-carbon nano-tube flexible transparent conductive film involves ultrasonically cleaning polyethylene glycol terephthalate (PET) substrate film by ethanol, drying, spraying mixed solution of graphene oxide (GO) and carbon nano-tube (CNT) on PET film substrate to form mixed layer of graphene oxide and carbon nano-tube (GO-CNT), processing with nitric acid (HNO3) at 10-12 megapascals (MPa), spraying poly 3,4-ethylene dioxythiophene (PEDOT) solution on surface of GO-CNT layer, diluting PEDOT solution to make it easier to spray, obtaining flexible conductive film with excellent conductivity by adding certain amount of ethylene glycol in PEDOT solution and using sulfuric acid (H2SO4) at 10-12 MPa after processing, preparing flexible conductive film of double-layer structure of GO-CNT mixed layer and PEDOT layer, where structure has more stable, high transmittance and low surface resistance, film preparation technique is simple, short period, high conductivity, when transmittance is 80-93%, surface resistance is 45-80 Omega/sq, surface roughness is less than 10 nanometer, where carbon nano-tube and poly 3,4-ethylene dioxythiophene is stacked by scanning electron microscope characterization found in transparent conductive film graphene oxide, and has high adhesive force dues to cross of each other forms stable three-dimensional structure.
