AI Technical Summary

Technical Problem

Existing hydrogels have shortcomings in terms of antibacterial and conductive properties, making it difficult to meet the needs of complex application scenarios in the fields of biomedicine and hygiene products. Furthermore, traditional conductive fillers can lead to a decrease in flexibility.

Method used

Ginkgo biloba natural extracts are copolymerized with imidazole alkenyl ammonium acid compounds, combined with organosilicon crosslinking agents and modifiers to form a gel with antibacterial and conductive properties. Electronic and ion conduction is achieved through flavonoids and terpenoids in the Ginkgo biloba natural extracts, while imidazole alkenyl ammonium acid compounds provide a stable three-dimensional network structure.

Benefits of technology

A low-toxicity, antibacterial, and conductive gel was prepared, which can effectively inhibit bacterial infection, promote cell migration and angiogenesis, and enable intelligent management. It is suitable for flexible electronic sensors and bioelectric stimulation dressings.

Abstract

The invention discloses a ginkgo natural extract copolymerized antibacterial conductive gel as well as a preparation method and application thereof. The conductive gel is prepared from the following raw materials in parts by mass: 1 to 10 parts of ginkgo natural extract, 1 to 8 parts of imidazolyl alkenyl amic acid compound, 0.02 to 0.1 part of stabilizer, 0.01 to 0.2 part of emulsifier, 0.5 to 1 part of organic silicon cross-linking agent, 1 to 5 parts of modifier, 0.05 to 0.3 part of organic oxidant, 1 to 10 parts of natural polysaccharide, 15 to 25 parts of organic solvent and 10 to 30 parts of water. The gingko natural extract has an antibacterial effect, micro-current is conducted by the gingko natural extract through a macromolecular chain and aromatic continuous conjugated structures in flavonoids and olefinic terpenoids, the antibacterial and conductive gel which is low in toxicity and can be applied to organism tissue repair is prepared, and the gel serving as a flexible medium can conduct electric signals and also can be used for repairing tissues of organisms. The foreign matter reaction risk can be reduced through the antibacterial function, meanwhile, the toxicity of metal ion leakage is avoided, and the method has unique advantages in the micro-current related fields such as flexible electronic sensors and bioelectrical stimulation dressings.
