Abstract

The invention relates to a transparent conductive film and a preparation method thereof, and belongs to the technical field of preparation of conductive films. With copper chloride as a copper source,oleic acid and oleylamine as inducers, glucose as a reducing agent and polyvinylpyrrolidone as a stabilizer, copper nanowires with high length-diameter ratio, uniform diameter, good dispersibility and regular morphology are prepared; through formation of a network with smaller linear density, a longer penetration path is provided, internal copper wire nodes are reduced, the resistivity is reduced, and a transparent metal film with low haze, high transparency, high conductivity and excellent mechanical flexibility and strength is achieved; then the copper nanowires are covered with an aqueouspoly(3,4-ethylenedioxythiophene)-polystyrene sulfonic acid solution to prepare a composite film to improve the oxidation resistance of the copper nanowires, so that the energy absorbing ability of themetal film layer during folding deformation is enhanced, the slippage degree of conductive particles is reduced, and thus the resistance change rate of a coating layer is reduced and the flexibilityand the electrical stability of a product are further improved.

Description

technical field [0001] The invention relates to a transparent conductive film and a preparation method thereof, belonging to the technical field of conductive film preparation. Background technique [0002] In nature, conductors are often opaque and poorly flexible, such as metal materials and graphite; while transparent materials are often non-conductive, such as glass and crystal. The emergence of transparent conductive film has broken people's traditional concept. It is a functional film with both light transmission and conductivity. [0003] As an important optoelectronic material, transparent conductive film has high light transmittance in the visible light region and high reflectivity in the infrared band. Due to these excellent photoelectric properties, transparent conductive films have been widely used in light-emitting diodes, light-emitting transistors, solar cells, touch screens and other fields. [0004] Transparent conductive films can be divided into oxide-ba...
