In recent years, rapid development of bioengineering has placed higher demands on transparency, flexibility, tensile properties, electrical conductivity and high biocompatibility of elastomers. The biological materials constructed by the eutectic solvent at present have the following important defects. Firstly, the composite material is prepared by adopting the eutectic solvent and natural macromolecules (chitosan, sodium alginate and the like), and the preparation steps are complicated and the cost is high. Secondly, most research has focused on developing novel ionic gels, involving less for liquid-free elastomers. The ionic gel constructed by the eutectic solvent often has the problems of liquid leakage, poor mechanical performance and the like. Thirdly, the development of the field in biological materials is limited due to the few varieties of high-biocompatibility eutectic solvents. Therefore, a new conductive elastomer with high light transmittance, high mechanical properties and conductivity is required to be searched.
