Description

technical field [0001] The invention belongs to the technical field of electronic adhesives, and in particular relates to a conductive silver paste for flexible electronic paper and a preparation method thereof. Background technique [0002] Compared with traditional rigid displays, flexible e-paper displays are soft, durable, thin, and novel in appearance. They are not only attractive to end users, but the development of flexible displays has also become an important layout point for the development of optoelectronic technology in developed countries or regions. Since flexible screens are required to be able to be bent, rolled and folded, and can be arranged randomly in three-dimensional space, and conductive silver paste is an indispensable core conductive material for flexible screens, this requires that it also has arbitrarily bendable, adhesive force. Good, stable conductivity and other characteristics, this is also a high-end product recognized by the world as having h...
