The invention discloses a novel flexible transparent electrode with a double-layer conductive network structure and a preparation method of the novel flexible transparent electrode. The novel flexibletransparent electrode comprises flexible transparent electrode with a novel double-layer conductive network structure and a preparation method of the flexible transparent electrode. The flexible transparent electrode comprises the novel double-layer network conductive structure; the novel double-layer network conductive structure is formed by compounding tannic acid functionalized carbon nanotubes and silver nanowires; a functionalized carbon nanotube conductive network at the bottom layer provides a conductive path for the silver nanowires and can be used as a conductive adhesive to increasethe conductive stability of a composite film and the adhesive force between the silver nanowires and a substrate, and a polyethylene terephthalate (PET) substrate film is ultrasonically cleaned withdistilled water and ethanol and then dried; The prepared tannic acid is used for modifying a carbon nano tube solution (TCNT). According to the flexible transparent electrode with the novel double-layer conductive network structure and the preparation method of the flexible transparent electrode, the conductive film is subjected to post-treatment through mechanical pressing and spraying of a poly3,4-ethylenedioxythiophene (PEDOT) solution, so that the transparent electrode with good adhesion, low surface roughness and high conductivity is obtained.
