Title:
METHOD FOR MANUFACTURING FLEXIBLE ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/077525
Kind Code:
A1
Abstract:
Disclosed is a method for manufacturing a flexible electronic device, comprising the following steps: 1) performing permeation treatment on a flexible substrate, and soaking the flexible substrate in 50% of a silver nitrate solution under the condition of a temperature of 40-50°C for 1 h to 1.5 h; 2) in the step 1), semi-soaking the flexible substrate in the silver nitrate solution; 3) taking out the flexible substrate, and standing for 10 to 15 minutes at normal temperature; and 4) forming an original region and a permeation region on the flexible substrate, a semi-permeation region being formed between the original region and the permeation region so as to form a whole, a position for mounting an element being provided in the semi-permeation region, and a modified film being provided at the position for mounting an element. According to the present invention, a semi-soaking process is performed on a flexible substrate of an electronic device by means of a silver nitrate solution, an original region and a permeation region are formed on the basis of the original flexible substrate, and a semi-permeation region is formed between the two regions, so that the toughness and durability of the flexible substrate can be improved, and the flexibility of the flexible substrate is maintained.
