Description

technical field [0001] The invention relates to the field of protective films, in particular to a flexible transparent conductive film and a preparation method thereof. Background technique [0002] Transparent conductive film is a kind of film that can conduct electricity and has high transparency in the visible light range. It is mainly used as a window material for optoelectronic devices (such as LEDs, thin-film solar cells, etc.); transparent conductive films that are widely concerned are mainly divided into Metal film system and oxide film system; Among them, the metal film system has good conductivity but poor transparency, while the oxide film system has high transparency and poor conductivity. At present, the common transparent conductive film is mainly ITO (tin-doped indium trioxide) transparent conductive film. This conductive film has a large band gap and only absorbs ultraviolet light, not visible light, so it is called "transparent". [0003] At present, tin-do...
