▎ 摘　　要

NOVELTY - Preparing macromolecule thermoelectric hydrogel based on ion conduction comprises polymerizing the macromolecule thermoelectric hydrogel with acrylamide (AAm) monomer by thermal initiation, crosslinking macromolecule hydrogel with the sodium alginate (SA) macromolecule, and soaking in a mixed aqueous solution of potassium ferricyanide, potassium ferrocyanide and guanidine hydrochloride and obtaining the macromolecule thermoelectric hydrogel. USE - The hydrogel is useful in thermoelectric material and device, sensing monitoring, heat dissipation and cooling, seawater desalination, thermal insulation, and wearable electronic (claimed). ADVANTAGE - The hydrogel: has excellent thermoelectric performance, simple preparation process, safety and harmlessness and can be mass-produced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a macromolecule thermoelectric hydrogel based on ion conduction prepared by the above preparation method.
