Buffer coating for transferring silver nanowire conducting layer and transfer method thereof

Abstract

The invention discloses a buffer coating for transferring a silver nanowire conducting layer and a transfer method thereof. A buffer coating with a special formula is arranged between a base film anda conducting layer of an existing silver nanowire transparent conducting film, so that the conducting layer can be transferred through a flexible transparent optical adhesive, and the flexible silvernanowire transparent conducting film which has better optical performance and flexibility and takes the flexible transparent optical adhesive as the substrate is obtained. Good adhesive force can be formed between the buffer coating and the base film, and the buffer coating cannot be synchronously transferred and taken away when the conductive layer is transferred; meanwhile, the surface tension of the buffer coating is moderate, thus facilitating coating of the conducting layer, and also as the buffer coating contains a very small amount of a fluorine-containing assistant, the adhesion between the conducting layer and the buffer coating is poor, and is conducive to subsequent transfer of the conducting layer.

Description

technical field [0001] The invention belongs to the field of flexible display, and in particular relates to a buffer coating for transferring a nano-silver wire conductive layer and a transfer method thereof. Background technique [0002] With the development of electronic display to large size and flexibility, the requirements for the flexibility of conductive films are getting higher and higher. At present, the ITO transparent conductive film with the largest amount in the market has the problems of high square resistance and poor flexibility, and is not suitable for large-size displays and flexible displays. The nano-silver wire in the new material has become the best substitute material for ITO due to its excellent comprehensive properties such as optical properties, good flexibility, and low square resistance. [0003] The square resistance of the nano-silver wire conductive film can be made very low, which is completely suitable for large-scale displays. However, the...

Problems solved by technology

Since the nano-silver wire itself has good flexibility, the flexibility of the conductive layer can fully meet any situation through modification, but the flexibility of the film substrate itself limits the flexibility of the nano-silver wire conductive film

[0004] In view of the limited flexibility of silver nanowire conductive film at present, it is urgent to develop a flexible transparent silver nanowire conductive film that is not limited by the flexibility of the base film, can be applied to any flexible display field, and has excellent performance.
