Abstract

The invention discloses a method for preparing a conductive polymer composite film and belongs to the technical field of electronic function materials. The method comprises the following steps of: adsorbing a polydiallyl dimethyl ammonium chloride film layer on a substrate, electrostatically adsorbing a poly(3,4-ethylenedioxythiophene) (PEDOT) or PEDOT-polystyrene sulfonate (PSS) film layer on the polydiallyl dimethyl ammonium chloride film, and alternately repeating the operation to obtain the conductive polymer composite film. The prepared conductive polymer composite film has high conductivity, high specific volume and high electrochemical performance, and the preparation method is simple and easy to operate and can be applied to electrodes of batteries, electrochemical capacitors and the like.

Description

technical field [0001] The invention belongs to the technical field of electronic functional materials, and relates to a conductive polymer film, especially a preparation method of a conductive polymer composite film. Background technique [0002] Conductive polymers not only have high electrical conductivity, but also have photoconductive properties, nonlinear optical properties, luminescent and magnetic properties, etc. Its good flexibility, low production cost and high energy efficiency make it not only in industrial production and military industry It has broad application prospects, and has great application value in daily life and civilian use. [0003] In 1991, German Bayer company first synthesized polyethylenedioxythiophene (PEDOT), a derivative of polythiophene, which has aroused widespread interest of scientists due to its high conductivity and good environmental stability. PEDOT has the characteristics of simple molecular structure, small energy gap, and high co...
