Abstract

The invention discloses a graphical fine electroconductive film. The graphical fine electroconductive film comprises a base and a graphical fine electrode. The graphical fine electrode is arranged on the base or embedded in the base. The width of the graphical fine electrode is 50 nanometers to 10 micrometers, the height thereof is 10 nanometers to 10 micrometers, and surface roughness thereof is 0.1 nanometer to 100 nanometers. The invention further discloses a production method of the graphical fine electroconductive film. The graphical fine electrode which has high transmittance, low square resistance and high flexural performance is realized; an etching process is avoided, environment friendliness is achieved, and electrode resolution ratio can reach 100 nanometers; the graphical fine electroconductive film is simple to operate and suitable for large-scale and low-cost production, and can be applied to application fields such as touch panels, solar cells, LED (light-emitting diode) display, OLED (organic light-emitting diode) display and QLED (quantum dot light-emitting diode) display.

Description

technical field [0001] The invention relates to the field of flexible electronics manufacturing, in particular to a method for preparing a patterned fine conductive film. Background technique [0002] Flexible electronics is a technology in which organic electronic devices or inorganic thin-film devices are fabricated on flexible substrates to form circuits. Since the performance of flexible electronic devices is comparable to that of traditional microelectronic devices, and has the characteristics of portability, transparency, light weight, stretch / bend, and easy rapid and large-area printing, it has attracted more and more attention from scientific research and industry. Its potential has been verified in the fields of flexible display and lighting, electronic paper, electronic skin, printed RFID, thin-film solar panels, etc., and has broad application prospects in information, energy, medical, national defense and other fields. [0003] Flexible electrodes or flexible tr...
