The present invention discloses a bending test apparatus and method for a flexible sheet material. The apparatus comprises a mounting table and further comprises a clamping unit and a bending shaft unit. The clamping unit comprises a clamping part. The bending shaft unit comprises a bending shaft extending in a Z-axis direction. The bending shaft has an arc-shaped sidewall for abutting against a flexible sheet material at an end thereof away from the clamping part. The clamping part moves relative to the bending shaft in a Y-axis direction. The present invention has the following advantage: During a test, a flexible sheet material is bent with a lower external strain, has a wide adjustment curvature range, and the structure is optimized.

Bending test apparatus and method for flexible sheet material

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.
