Patent ID: 11845843

Abstract:
The present invention provides a method for preparing a conductive silk fibroin material, comprising the steps of: (1) preparation of a high-molecular-weight silk fibroin solution; (2) preparation of an insoluble silk fibroin material; (3) surface treatment of the silk fibroin material; (4) oxidation of the silk fibroin material; and (5) in-situ oxidative polymerization of 3,4-ethylenedioxythiophene on the surface of the graft-modified silk fibroin material. In the present invention, a conductive composite film grafted with 3,4-ethylenedioxythiophene on the surface is prepared, and the surface resistance is 100 to 5000 ohms. The preparation process is simple and mild, and the obtained conductive silk fibroin material can be used as a flexible electronic device, especially as a device for measuring human blood glucose level and heartbeat.
