Embodiment 1

[0031] (1) In the three-electrode electrolytic cell system, EDOT (0.07109g, 0.5mmol) was used as a monomer, and LiClO 4 (1.0640g, 0.01mol) as the supporting electrolyte, with acetonitrile (100mL) as the electrolytic solvent, 100mL of a mixed solution with a monomer concentration of 5mmol / L and a supporting electrolyte concentration of 0.1mol / L was prepared as the electrolyte, and ITO conductive glass was used as the working Electrode, with platinum electrode as auxiliary electrode, silver / silver chloride electrode as reference electrode, saturated potassium chloride aqueous solution as the first liquid junction, and the electrolyte as the second liquid junction. At room temperature, the electrochemical polymerization reaction is carried out by cyclic voltammetry anodic oxidation polymerization. The blue polymer film on the electrode was rinsed with acetonitrile to remove the residual electrolyte on the surface of the polymer film and dried in a vacuum drying environment at 60°...

Abstract

The invention discloses a poly-3,4-ethylenedioxythiophene nano mesh structure film as well as a preparation method and an application thereof. The poly-3,4-ethylenedioxythiophene is of a nano mesh structure. The poly-3,4-ethylenedioxythiophene film is specifically prepared by the following steps: by taking 3,4-ethylenedioxythiophene as a monomer in a three-electrode cell system, taking lithium perchlorate as supporting electrolyte, and taking acetonitrile as an electrolytic solvent, uniformly mixing to obtain electrolyte; and by taking an indium tin oxide conductive glass electrode as a working electrode, taking a platinum electrode as an auxiliary electrode, and taking a silver/silver chloride electrode as a reference electrode, carrying out an electrochemical polymerization reaction at aroom temperature by adopting cyclic voltammetry or a potentiostatic method, thereby obtaining a polymer film deposited on the working electrode, eluting, and drying, thereby obtaining the poly-3,4-ethylenedioxythiophene. The conductive polymer film prepared by the method disclosed by the invention has a special nano mesh structure. Compared with an ordinary plane structure, the conductive polymerfilm has excellent electrochromic property.
