Bifunctional polyaniline electroconductive hydrogels with applications in supercapacitor and wearable strain sensors.

In this article, bifunctional polyaniline/polyacrylamide (PANI/PAAm) hydrogel is fabricated. The hydrogel has capacitive performance and can be used for monitoring human motions. The effect of PANI doped with two different acids on the properties of hydrogels was researched.
