Abstract

The invention discloses a polymerizable eutectic solvent, a conductive elastomer and a preparation method thereof. The polymerizable eutectic solvent is obtained by blending a hydrogen bond acceptor and a hydrogen bond donor at 60-100 DEG C, the hydrogen bond acceptor comprises polycarboxylic acid choline and/or polycarboxylic acid betaine, the hydrogen bond donor comprises an imidazole monomer, and the molar ratio of the hydrogen bond donor to the hydrogen bond acceptor is not less than 1: 1. The elastomer comprises the polymerizable eutectic solvent, a cross-linking agent and an initiator, and is prepared under light or heat curing. The conductive elastomer prepared from the polymerizable eutectic solvent has unique ionic conductivity, good optical transparency and biocompatibility, and has wide application prospects in biosensors, wound healing, cell tissue engineering and motion monitoring.

Description

technical field [0001] The invention relates to a polymerizable low eutectic solvent, a conductive elastomer and a preparation method thereof, belonging to the technical field of ionic liquids. Background technique [0002] Deep eutectic solvents belong to the subclass of ionic liquids, which inherit the chemical stability and high conductivity of ionic liquids, and also have the advantages of low cost, 100% atom utilization, and simple preparation, which ionic liquids do not have. At present, the research on deep eutectic solvents mainly focuses on the fields of gas capture, biomass extraction and dissolution, and catalysis. The polymerizable deep eutectic solvent refers to a deep eutectic solvent capable of forming a conductive elastomer through polymerization after adding an initiator. At present, there are few reports on polymerizable deep eutectic solvents. [0003] Highly transparent, stretchable, conductive, and highly biocompatible elastomer materials have broad de...
