Abstract

The invention discloses a flexible transparent electrode and a preparation method thereof and electronic skin. The flexible transparent electrode comprises a flexible substrate, wherein a metal conductive material layer is bonded to the surface of the flexible substrate, the metal conductive material layer is in a plant vein-shaped pattern, and a metal conductive material is a silver nanowire. The flexible transparent electrode has excellent conductivity and light transmittance performance, and also has excellent flexibility and mechanical stability. According to the preparation method of the flexible transparent electrode, the stable performance of the prepared flexible transparent electrode and the environmental protection and safety in the preparation process are ensured; the preparation technology is simple and high in speed; the preparation method only needs to be carried out at a room temperature; and abundant leaf vein templates in the natural world are utilized, so that the cost is low and the flexible transparent electrode is suitable for green and low-cost mass production. The electronic skin containing the flexible transparent electrode disclosed by the invention is sensitive in induction, and the bionic effect is excellent due to high transparency of the electrode.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to a flexible transparent electrode and its preparation method and application. Background technique [0002] Metal oxides, especially ITO (Indium Tin Oxide) are currently the most widely used transparent electrode materials, often used in a series of related technologies such as flat panel displays, solar cells, organic light-emitting diodes, etc. as an N-type oxide material semiconductor. When ITO is used as an electrode, the light transmittance and conductivity are often determined by In 2 o 3 with Sn 2 o 3 The ratio is controlled, and the process is generally prepared by vacuum evaporation. [0003] Indium in ITO is a scarce element, its content on the earth is decreasing day by day, and its price is gradually rising, which does not meet the demands of low-cost mass production. In addition, ITO itself is hard, brittle, and not easily deformed, so it...
