Abstract
The invention provides a transparent conducting film. The transparent conducting film is prepared by coating a transparent substrate with silver nano wire slurry through a coating element, wherein the surface of the coating element is processed through hydroxylation. The specific preparation method comprises the following steps: performing standardized cleaning for the coating element; performing surfactant carboxylation processing for the surface of the coating element; preparing AgNWs suspending liquid; locating the transparent substrate horizontally, and dropping the prepared AgNWs suspending liquid on the transparent substrate, and coating the surface, and processed through surfactant carboxylation processing, of the coating element, with silver nano wires on the transparent substrate; and finally performing drying processing. The transparent conducting film is high in light transmittance and conductivity; the sheet resistance of the transparent conducting film is 6-15 omega / sq; the average transmittance of the visible wavelength is greater than 70%; and the transparent conducting film can be applied in more occasions, and is high substitutability for current ITO and FTO conducting films, and can be applied to a plurality of novel industrial products.
Description
technical field [0001] The invention belongs to the technical field of transparent conductive films, in particular to a transparent conductive film loaded with silver nanowires and a preparation method. Background technique [0002] The transparent conductive film (TCF) refers to a transmittance of 70-90% for visible light with a wavelength range of 380-780nm, and a surface resistance of 4-1000Ω / sq. [0003] Transparent conductive films are widely used in touch liquid crystal panels, organic light emitting diodes (OLEDs), organic photovoltaic devices (OPVs), and electromagnetic shielding. At present, transparent TCF can be divided into: oxide semiconductor film (TCO), metal film, metal composite film, polymer film and carbon nanotube film (CNT), graphene film (Graphene), metal film according to different conductive materials. line film etc. [0004] The metal transparent conductive film has good conductivity, but the transmittance is low, and the strength and hardness of p...
