Embodiment 1
[0055] Such as figure 1 , figure 2 As shown, a stretchable micro-supercapacitor includes a stretchable electrode 1, an electrolyte 2 and a stretchable substrate 3, the stretchable electrode 1 is arranged on the stretchable substrate 3, and the electrolyte 2 is coated with On the stretchable electrode 1, both the stretchable electrode 1 and the stretchable substrate 3 are three-dimensional structures prepared by inversion molding, the stretchable electrode 1 is a silica gel-based conductive compound, and the silica gel-based The conductive composite includes an electroactive material and silicone rubber, the electroactive material is a mixture of polyaniline and carbon nanotubes, the stretchable substrate 3 is silicone rubber, and the silicone rubber adopts Ecoflex series.
[0056] In this embodiment, the weight ratio of the polyaniline to the carbon nanotubes is 3:1, the weight ratio of the electroactive material to the silicone rubber is 1:5, and the carbon nanotubes are mu...
Embodiment 2
[0084] This embodiment is based on embodiment 1, and the difference with embodiment 1 is:
[0085] The weight ratio of the polyaniline to the carbon nanotube is 1:1, and the weight ratio of the electroactive material to the silicone rubber is 1:5.
[0086] S1. Preparation of stretchable silica gel-based composite:
[0087] 1) Weigh 5g of Ecoflex 00-30 series Part A solution, put it in a 50ml beaker, and homogenize it on a constant temperature magnetic stirring table at a speed of 300rpm for 2min;
[0088] 2) Weigh 1g of carbon nanotubes, add an average of 0.01g to the Part A solution, and adjust the rotation speed to 700rpm;
[0089] 3) After the carbon nanotubes are uniformly dispersed in the Part A solution, weigh 1 g of polyaniline, and add 0.01 g on average to the above mixed solution. After the solution is uniformly mixed, the carbon nanotubes and polyaniline are added gradually and repeatedly. When the solution becomes viscous, constantly adjust the rotation speed to ...
Embodiment 3
[0094] This embodiment is based on embodiment 1, and the difference with embodiment 1 is:
[0095] The weight ratio of the electroactive material to the silicone rubber is 1:8.
[0096] S1. Preparation of stretchable silica gel-based composite:
[0097] 1) Weigh 8g of Ecoflex 00-30 series Part A solution, put it in a 50ml beaker, and homogenize it on a constant temperature magnetic stirring table at a speed of 300rpm for 2min;
[0098] 2) Weigh 0.5g of carbon nanotubes, add an average of 0.01g to the Part A solution, and adjust the rotation speed to 700rpm;
[0099] 3) After the carbon nanotubes are uniformly dispersed in the Part A solution, weigh 1.5 g of polyaniline, and add an average of 0.01 g to the above mixed solution. After the solution is uniformly mixed, the carbon nanotubes and polyaniline are added gradually and repeatedly. When the solution becomes viscous, constantly adjust the rotation speed to fully mix the solution until the carbon nanotubes and polyanilin...
