C-SF-FA flexible conductive film based on silk fibroin, wearable wound monitoring sensor and preparation method thereof

Abstract

The invention discloses a C-SF-FA flexible conductive film based on silk fibroin and a monitoring sensor made of the C-SF-FA flexible conductive film. The C-SF-FA flexible conductive film is preparedby the following steps of: 1) degumming silk, dissolving the silk in a salt-formic acid system to obtain a silk fibroin solution, performing drying to obtain silk fibroin, soaking the silk fibroin indeionized water, and dissolving the dried silk fibroin in formic acid again to obtain an SF-FA electrospinning solution; 2) dissolving dopamine in water, and adding carbon nanotubes to obtain a DA-CNTsolution; (3) preparing the SF-FA electrospinning solution into a flexible film through electrospinning, and spraying the DA-CNT solution onto the film for multiple times in the electrospinning process; airing the film to obtain a C-SF-FA conductive film; and 4) adding DA and CNT into an alkaline solution to obtain a PDA-CNT solution, soaking the C-SF-FA conductive film in the PDA-CNT solution, performing cleaning and drying, conducting soaking in an ethanol or methanol solution, and performing drying.

Description

technical field [0001] The invention relates to the technical field of biomaterials, in particular to a silk fibroin-based C-SF-FA flexible conductive film, a wearable wound monitoring sensor and a preparation method thereof. Background technique [0002] The skin is the first barrier of human immunity and plays a pivotal role in protecting people's health. When the skin is damaged beyond repair, it will have a great impact on the body's interest-free system. Chronic wounds are a relatively common skin injury. For relatively minor burns, the skin will be repaired in an orderly manner. However, when the wound area is too large and too deep, the patient's own healing ability will not be enough to repair, which will be harmful to the patient. lives are threatened. Therefore, the treatment and monitoring of chronic wounds has received extensive attention from countries all over the world. [0003] Wound healing is a continuous and overlapping dynamic process that includes thr...
