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.

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

A preparation method of a conductive elastomer includes the following steps: (1) according to the mass percent of 20&#x2dc;75%, dissolving the metallic salts into deionized water to form an electrolyte solution, wherein said metallic salts is either of magnesium nitrate, sodium nitrate, zinc nitrate, cesium nitrate, calcium nitrate, neodymium nitrate, aluminum nitrate, potassium nitrate, potassium chloride, magnesium chloride, calcium chloride, sodium chloride, zinc chloride, cesium chloride, aluminum chloride or their combinations; (2) according to the mass percent of 10&#x2dc;40%, mixing starches into the electrolyte solution prepared in step (1), then at the temperature of 33&#x2dc;120&#xb0; C., stirring to gelatinize the starches, forming a viscous liquid; (3) standing the viscous liquid obtained in step (2) at 25&#x2dc;90&#xb0; C. for 10 min to 48 h to obtain the conductive elastomer.
