Flexible electrode and preparation method thereof

Abstract

The invention provides a flexible electrode and a preparation method therefor, and the method comprises the following steps: S1, spraying a metal nanowire solution on the surface of modified glass, putting the modified glass into a drying box for drying, performing cooling after drying, and forming a metal nanowire layer; S2, preparing a thermoplastic elastomer solution; S3, printing a thermoplastic elastomer solution on the metal nanowire layer by adopting a silk-screen printing mode, and performing heating and curing to enable the thermoplastic elastomer solution to form an elastic protective layer with a predetermined pattern on the metal nanowire layer; S4, putting the metal nanowire layer with the protective layer into a metal etching solution for etching to form a metal nanowire electrode with a predetermined pattern; S5, pouring a thermoplastic elastomer solution into the metal nanowire electrode, and drying and curing the metal nanowire electrode; S6, stripping the metal nanowire electrode from the surface of the modified glass to obtain the flexible electrode. The preparation method of the flexible electrode is few in steps, flexible in electrode style, low in whole manufacturing cost and beneficial to wide application.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a preparation method of a stretchable flexible metal electrode. Background technique [0002] In recent years, with the rapid development of emerging fields such as wearable electronic devices, smart electronic skin, and robots, the application of flexible and stretchable electronic devices has attracted extensive attention. Compared with traditional electronic devices, stretchable electronic devices break through the limitation of rigid silicon substrates and can maintain normal operation under tension, compression, bending and other states. Therefore, flexible and stretchable electronics have great application potential in many fields. Among them, flexible electrodes are particularly important as the basis of flexible and stretchable electronic devices. [0003] Most of the existing flexible electrodes are made of polymers, and are prepared based on the patterned cir...
