Abstract

The invention discloses a flexible substrate used for optoelectronic devices and comprises a flexible substrate; the invention is characterized in that a bonding layer and a conductive thin film are arranged on the surface of the flexible substrate; the conductive thin film is deposited on the surface of the bonding layer; and the material of the bonding layer is an adhesive with a double-curing system comprising UV curing-thermal curing or UV curing-microwave curing or UV curing-anaerobic curing or UV curing-electron beam curing. The substrate solves the problem of poor adhesion between the deposited conductive thin film and the substrate due to low surface energy of the flexible substrate and improves the barrier properties of the substrate on water and oxygen, and also achieves good smoothing effect on the surface of the substrate; besides, the preparation method is simple and effective, which can significantly reduce the substrate production cost and process difficulty and increase the substrate yield rate in the etching process.
