Description

technical field [0001] The invention relates to a composite transparent conductive film of silver nanowires and transparent conductive oxides and an application thereof, belonging to the field of optical technology. Background technique [0002] Transparent conductive films are widely used in fields such as display devices, dimming glass and solar cells due to their high light transmittance and good electrical conductivity. The current transparent conductive films are mostly sputtered transparent conductive oxides (TCO) on plastic or glass, mainly indium tin oxide (ITO), F-doped ZnO (FZO), Al-doped ZnO (AZO), etc., although transparent Electrical conductivity, but its production process is complicated, the cost is high, and the square resistance is generally large, brittle, and cannot be bent. [0003] Silver nanowires are a new type of conductive nanomaterials, with diameters ranging from 10 to 500 nanometers and lengths ranging from a few microns to hundreds of microns. ...
