Embodiment 1
[0101] (1) Preparation of flexible and stretchable electrodes
[0102] Silicon wafer cleaning: Scrub a 15mm×14mm silicon wafer with absolute ethanol, then put it into deionized water for ultrasonic cleaning for 10 minutes, then blow dry the residual ethanol on the silicon wafer with nitrogen, and then put it in acetone After performing ultrasonic cleaning for 10 minutes, dry the residual acetone on the silicon wafer with nitrogen gas. Finally, put it into isopropanol for ultrasonic cleaning for 10 min, and then use nitrogen gas to dry the residual isopropanol on the silicon wafer.
[0103] The preparation of mixed solution: with 4mg graphite powder nanosheet (its SEM picture is as follows image 3 As shown, it can be seen that it has a lamellar structure) was added to 4mL of deionized water, and the first ultrasonic crushing and the second ultrasonic crushing were carried out successively with a power of 400W in the ultrasonic cell pulverizer, and the first ultrasonic pulveriz...
Embodiment 2
[0112] (1) Preparation of flexible and stretchable electrodes
[0113] Different from Example 1, the concentration ratio of graphite powder nanosheets and silver nanowires in the mixed solution is 1:0.8, that is, the addition of graphite powder nanosheets is 4mg, the addition of silver nanowires is 3.2mg, and the rest Step is identical with embodiment 1.
[0114] (2) Stress tensile performance test
[0115] The stress-stretching performance of the flexible stretchable electrode was tested by using a precision electric translation stage and a two-phase stepping motor controller, and the resistance change of the flexible stretchable electrode was measured by a digital power meter. The resistance change diagram of the flexible stretchable electrode electrode under 0%-40% stress stretching is as follows Figure 7 As shown, the horizontal axis is the stress stretching Strain, ranging from 0% to 40%, and the vertical axis is the resistance value Resistance of the flexible stretcha...
