▎ 摘　　要

NOVELTY - Preparing fibroin flexible electrode, comprises: (i) degumming mulberry silkworm silk, dissolving, filtering, ultra-filtering, and desalting to prepare fibroin aqueous solution; (ii) preparing fibroin masterbatch by adding plasticizer to fibroin aqueous solution, completely stirring, uniformly mixing, and then using granulator for spray drying and one-step granulation; (iii) pressing the prepared fibroin masterbatch to obtain fibroin substrate film; (iv) plasma processing the fibroin substrate film; (v) preparing coating conductive solution; and (vi) preparing conductive structure by pasting a mask plate on the plasma processed fibroin substrate film, then coating the reduced graphene oxide fibroin conductive solution obtained in step (v), drying, and removing the mask plate. USE - The fibroin flexible electrode is useful for monitoring muscle nerve injury, repairing tissue, delaying senility, and skin whitening. ADVANTAGE - The fibroin is simple in structure and convenient to use, has high sensitivity and good affinity for skin, and can be worn for a long time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a fibroin flexible electrode, prepared by the above-mentioned method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a fibroin flexible electrode.
