Abstract

The invention discloses a metal mesh transparent electrode with a modified PEDOT:PSS protective layer and a preparation method thereof and belongs to the technical field of metal mesh transparent electrodes. The preparation method comprises neutralizing a PEDOT:PSS aqueous solution with a pH of 7.0-7.5 through a strongly basic solution containing NH2+ and NH3+ groups to a pH of 7.0-7.5; doping thePEDOT:PSS aqueous solution with the pH of 7.0-7.5 to obtain a modified PEDOT:PSS aqueous solution, then applying the modified PEDOT:PSS aqueous solution onto a metal mesh transparent electrode, and performing drying treatment to form a uniform modified PEDOT:PSS film on the metal mesh transparent electrode as the protective layer. By adding the modified PEDOT:PSS protective layer onto the metal mesh transparent electrode, the long-term application stability of the metal mesh transparent electrode can be enhanced. The preparation method of the metal mesh transparent electrode with the modifiedPEDOT:PSS protective layer is applied to processing metal mesh transparent electrodes.

Description

technical field [0001] The invention relates to a metal grid transparent electrode with a modified PEDOT:PSS protective layer and a preparation method thereof, belonging to the technical field of metal grid transparent electrodes. Background technique [0002] Transparent electrodes are an indispensable and important component in the modern electronics manufacturing industry. They are required to have good conductivity and transparency. When applied to electronic devices, they can block electronic radiation, ultraviolet rays and far infrared rays that are harmful to the human body, thus effectively Reduce the harm of electronic products to human body. Its application range covers many fields such as display panels, solar cells, light-emitting diodes and various sensors. [0003] Metal materials contain a large number of free electrons, so most metals are very good conductive materials. The use of metal networks to prepare transparent electrodes can ensure low surface resist...
