Abstract

Disclosed is a flexible substrate/liquid electrolyte viscous composite material and preparation method therefor. The preparation method includes: adding a particular percentage by weight of a flexible substrate to a liquid electrolyte solution having a particular concentrate; fully stirring the solution at a particular temperature to dissolve and evenly disperse the substrate, so as to obtain a viscous liquid; and then standing the viscous liquid at a particular temperature for a particular period of time to obtain the material. The material has viscosity due to which the material can actively adhere to the surface of tissue of an organ, the mechanical property matching cardiac muscle, biocompatibility and security, and is used for treating acute and chronic myocardial infarction and heart failures, inhibiting the reconstruction, thinning, and fiberization of a ventricular wall, and improving the myocardial function. In addition, the material also features conductivity, in vivo degradability, and the like.
