AI Technical Summary

Technical Problem

Traditional conductive hydrogels are prone to water loss under natural air conditions, resulting in poor mechanical strength, which affects their flexibility and conductivity, limiting their application in complex environments.

Method used

Animal skin was used as the base material, and its natural collagen fiber three-dimensional network structure was utilized. A deep eutectic solvent was used instead of water as the dispersion and conductive medium to prepare a skin-based eutectic gel, forming an interpenetrating network structure.

Benefits of technology

The prepared skin-based eutectic gel has high mechanical strength, good flexibility and conductivity, good environmental stability, and is suitable for long-term use in complex environments. The raw materials are natural, low in toxicity, biodegradable, low in cost, and the process is simple and easy to industrialize.

Abstract

This invention relates to a method for preparing a skin-based eutectic gel. The method uses deacidified naked hide as raw material, with an impregnation solution composed of monomers, an initiator, and water, and a deep eutectic solvent composed of choline chloride and glycerol in a molar ratio of 1:2. The deacidified naked hide is placed in the impregnation solution and stirred at 10-30°C for 1-6 hours. The impregnated hide is then heated at 40-70°C for 2-12 hours to obtain a skin-based hydrogel. Subsequently, the skin-based hydrogel is placed in the deep eutectic solvent and stirred at 10-30°C for 24-48 hours, obtaining the skin-based eutectic gel through solvent displacement. The skin-based eutectic gel prepared by this method inherits the excellent mechanical strength and flexibility of animal hide and the good electrical conductivity and environmental stability of the deep eutectic solvent. Its raw materials are natural, low in toxicity, biodegradable, and inexpensive, possessing the advantages of being green and sustainable. Furthermore, the raw materials are readily available, the formulation is simple and inexpensive, the process is simple, and it is easy to industrialize.
