Abstract

The invention provides anti-freezing viscous flame-retardant conductive polymer gel as well as a preparation method and application thereof. The conductive polymer gel is prepared from the following raw materials in percentage by mass: 20-60% of solvent, 3-20% of acrylamide monomer, 2-10% of imidazole monomer, 5-30% of conductive polymer monomer or salt thereof, 10-30% of ferric salt and 0.1-1% ofinitiator. The conductive polymer gel disclosed by the invention has anti-freezing viscosity and also has environment resistance, self-repairing performance and flame retardance, and the gel can be widely applied to the fields of electronic conductive adhesives, electrode materials, electronic wires, wearable devices and the like.

Description

technical field [0001] The invention relates to the technical field of adhesive polymers, in particular to a freeze-resistant viscous flame-retardant conductive polymer gel and its preparation method and application. Background technique [0002] Due to its unique three-dimensional network structure, the double-network gel often has excellent mechanical properties such as high scalability, adjustable strength and flexibility due to polymer chain entanglement and multiple cross-linking mechanisms. , self-healing and other properties, it has a wide range of applications in wearable devices, biomedical materials, adhesives, clean energy and other fields. However, the mechanical properties of many hydrogels drop sharply below the freezing point of water, because the solidified crystals significantly inhibit the fluidity of the hydrogel network, thus making the material brittle. In addition, due to the highly confined polymer chains, the conductivity and adhesion of hydrogels ar...
