Abstract

The invention discloses a silk fibroin conductive hydrogel and a preparation method thereof. The silk fibroin conductive hydrogel is a silk fibroin conductive hydrogel constructed by using a silk fibroin molecule as a matrix, and introducing a host, a guest, a horseradish peroxidase and a polyphenol-modified graphene nanosheet in an amino acid side chain of the silk fibroin molecule, and has bothsuper-strong stretching and self-attaching functions. The prepared hydrogel has a conductivity of 10 s / m, and has good mechanical properties, the tensile deformation capacity can be up to 500%, and the hydrogel can be closely attached to the surface of human tissues or other articles, and can be repeatedly attached. More importantly, the hydrogel material can still retain excellent electrical conductivity, tensile resistance and self-attaching properties under high frequency use. The preparation of the silk fibroin conductive hydrogel provides a better material platform for production and application of a new generation of flexible bio-electronic products.

Description

technical field

[0001] The invention relates to the technical field of biomaterials, in particular to a silk fibroin conductive hydrogel and a preparation method thereof. Background technique

[0002] In recent years, with the rise of wearable electronics and Internet of Things technologies, the application of flexible devices in medical diagnosis, motion monitoring, intelligent robots and other fields has received more and more attention. Conductive hydrogel is an ideal interface material for perfect compatibility between the human body and bioelectronic devices, and can perfectly fit the skin to detect corresponding physiological stimuli. In order to achieve long-term stable and efficient human-computer interface interaction, conductive hydrogels need to possess good biocompatibility, toughness, excellent stability, and high electrical conductivity. However, the existing conductive hydrogels have low elongation and are prone to permanent damage under high-frequency use, a...
