Natural polymer conductive hydrogel with powder self-healing performance as well as preparation method and application of natural polymer conductive hydrogel

The invention provides natural polymer conductive hydrogel with powder self-healing performance as well as a preparation method and application of the natural polymer conductive hydrogel. Natural polymer chitosan is taken as a raw material, methacrylic acid is taken as a functional monomer, zinc salt is taken as an electrolyte, and an initiator, deionized water and acid are taken as auxiliary raw materials, so that the recyclable natural polymer conductive hydrogel with excellent mechanical properties and powder self-healing performance is prepared. The conductive hydrogel not only has excellent mechanical properties and electrical conductivity, but also has excellent self-healing performance, and the hydrogel can be quickly self-healed after being damaged; the hydrogel also shows excellent powder self-healing performance, and keeps stable mechanical properties and electrochemical properties. The preparation process is simple, convenience is provided for large-scale application of the natural polymer conducti
