Problems solved by technology

However, AgNWs also has its own disadvantages: the stacking of nanowires will cause the surface roughness of the nanowire network to be large, which is often easy to cause short circuit of the device; in addition, AgNWs are easily oxidized when exposed to the air environment. If it is in a high temperature and high humidity environment, The oxidation of AgNWs will be more serious, which will greatly damage the performance of AgNWs conductive network.
For example, Lee et al. used the layer-by-layer self-assembly (LBL) method to deposit graphene oxide GO on the silver nanowire film, and obtained a composite electrode with good mechanical stability, but a certain thickness GO will reduce the photoelectric performance of silver nanowire electrodes (Adv. Mater. 2015, 27, 2252–2259); Kim et al. used the method of sputtering zinc oxide (ZnO) to prepare

Description

technical field [0001] The invention belongs to the technical field of electronic devices, and in particular relates to a silver nanowire-biological material composite transparent conductive film and a preparation method and application thereof. Background technique [0002] ITO (Indium Tin Oxide) has high visible light transmittance and high electrical conductivity. It is often used as electrodes for devices such as OLEDs, solar cells, touch screens and sensors, and occupies a large market share. However, indium resources are scarce, brittle, and the preparation process is complicated, which greatly limits its application in the field of flexible electronics. Researchers are working on the development of second-generation flexible transparent electrodes, such as flexible transparent conductive materials such as carbon-based materials, metal nanowires, ultrathin metals, and conductive polymer electrodes. [0003] Among these flexible transparent electrode materials, silver ...
