Electrically conductive hydrogel composition, self healing electrically conductive hydrogel prepared therefrom, and hydrogel-based triboelectric nanogenerator

Abstract

A electrically conductive hydrogel composition includes: a polar polymer selected from the group consisting of polyvinyl alcohol, polyacrylic acid, polyethylene oxide, poly(2-acrylamido-2-methyl-1-propane sulfonic acid), and combinations thereof; a gelatin; a binding agent including tannic acid and dopamine; a hygroscopic agent including ethylene glycol; a strong electrolyte; and water. A self-healing electrically conductive hydrogel prepared from the electrically conductive hydrogel composition is also provided. A hydrogel-based triboelectric nanogenerator including a self-healing electrically conductive hydrogel film that is made from the self-healing electrically conductive hydrogel is also provided.
