Title:
STRETCHABLE, COMPRESSIBLE AND ANTIFREEZING ORGANIC HYDROGEL ELECTROLYTE, PREPARATION METHOD AND APPLICATION
Document Type and Number:
WIPO Patent Application WO/2023/019676
Kind Code:
A1
Abstract:
The present invention belongs to the field of functional polymer hydrogels, and in particular relates to a stretchable, compressible and antifreezing organic hydrogel electrolyte, a preparation method and an application. The organic hydrogel electrolyte provided by the present invention is formed by means of the free radical-initiated polymerization of methacryloylethyl sulfobetaine and acrylamide using dimethyl sulfoxide and water as solvents, and a cross-linked network is doped with soybean protein. The organic hydrogel electrolyte provided by the present invention has a maximum fracture strain of up to 762.5%, may still be restored to an original state after undergoing 500% tensile or 80% compressive strain multiple times, and has excellent mechanical properties. The room temperature conductivity may reach 37.5 mS•cm-1. At -20°C, the charge and discharge time is still 13 s. Therefore, the organic hydrogel electrolyte has good low-temperature electrical properties, and may achieve the technical effect of acting as a supercapacitor electrolyte; and the organic hydrogel electrolyte has strain sensitivity, and may achieve the technical effect of acting as a stable sensor material.
