Description

technical field [0001] The invention relates to a preparation method of a nano conductive composite film. Background technique [0002] There are many definitions of conductive film, some refer to "a conductive film that can realize some specific electronic functions", and some refer to "'multi-layer' films of input devices such as keyboards, and some are single-layer". In recent years, many scientists have devoted themselves to the research and development of conductive thin film materials, but their applications have been restricted due to the poor processability and low mechanical properties of conjugated conductive polymers. The preparation of conductive components with biological templates not only has a novel structure, high transparency and good conductivity, but also overcomes the shortcomings of poor processability and low mechanical properties. Therefore, its preparation method and its application in conductive films are of great significance. Contents of the inv...
