Preparation device of flexible electrode and method for preparing flexible electrode by using preparation device

Abstract

The invention provides a preparation device of a flexible electrode. The preparation device comprises a mixing container, a deposition container, a current detector, a first heater and/or a second heater, wherein a flow pipeline and a valve for closing or opening an inlet end of the pipeline are arranged at the bottom end of the mixing container; a liquid metal and an elastomer are stirred and mixed evenly in the mixing container; a probe detects a mixture until current passes through an ampere meter; and the valve of the pipeline is opened and the mixture flows to the deposition container through the pipeline under the pressure effect and is molded into a block electrode. Compared with the prior art, the preparation device is simple in structure, the electrode can be produced on a large scale and the electrode has the advantages of high deformability, stable resistance and the like.

Description

technical field [0001] The invention relates to the technical field of flexible electronics, in particular to a device for preparing flexible electrodes and a method for preparing flexible electrodes using the device. Background technique [0002] As an emerging technology, flexible electronics has attracted more and more attention worldwide, especially with the rise of wearable devices, the requirement for full flexibility of electronic devices is becoming more and more urgent. [0003] In order to achieve full flexibility of electronic devices, electrode materials, as an integral part of electronic devices, also urgently need to be flexible. There are mainly two types of flexible electrode materials that have been reported so far: one is electrode materials that can undergo bending deformation, such as ITO that can be used as transparent and flexible electronic displays, etc. This type of electrode materials can be bent to a certain extent, but It is still far from meetin...

Problems solved by technology

There are mainly two types of flexible electrode materials that have been reported so far: one is electrode materials that can undergo bending deformation, such as ITO that can be used as transparent and flexible electronic displays, etc. This type of electrode materials can be bent to a certain extent, but It is still far from meeting the stretchable requirements of flexible electronic devices in practical applications; the other type is stretchable electrode materials, but the resistance of these stretchable electrodes reported so far is large, most of them are semiconductor materials, and these flexible The resistance of the electrode changes greatly when stretched, which is very unfavorable for its application in flexible electronic devices
