Flexible substrate/liquid electrolyte viscous composite material and preparation method thereof

The invention discloses a flexible substrate/liquid electrolyte viscous composite material and a preparation method thereof. The material has viscidity and can be autonomously attached to the surface of organ tissues, has the strength matching the cardiac muscle, and has biological compatibility and security. Meanwhile, the invention relates to the preparation method of the material. The method comprises: adding a specific organic matter into a specific electrolyte solution with a certain concentration according to a certain mass percentage; performing full stirring to dissolve or uniformly disperse the substrate at a certain temperature and obtaining a viscous liquid; and performing standing for a certain time at a specific temperature and obtaining the material. The material can be used for curing acute and chronic myocardial infarction and cardiac failure, inhibits reconstitution, attenuation, and fibrosis of the ventricular walls, and improves functions of the cardiac muscle. Meanwhile, the material has characteristics of electrical conductivity and in-vivo degradation.
