Problems solved by technology

However, due to the difference in elastic modulus between the nano-conductive particles and the polymer, the conductive performance of the prepared elastic conductive material becomes poor during the long-term folding cycle; the same nano-conductive particles are easy to react with various substances in the air to reduce the conductivity. And the price of nanoparticles is higher

Abstract

The invention discloses application of polymerizable deep-eutectic solvents to preparing transparent conductive elastomers. Hydrogen bond receptors and hydrogen bond donors are mixed with one another at the temperatures of 60-100 DEG C to obtain the polymerizable deep-eutectic solvents, a molar ratio of the hydrogen bond donors to the hydrogen bond receptors is not smaller than 1:1, and the hydrogen bond donors comprise acrylic acid or methacrylic acid. The polymerizable deep-eutectic solvents, cross-linking agents and photoinitiators are mixed with one another to obtain mixed solution, and the mixed solution can be cured in polytetrafluoroethylene culture dishes under ultraviolet irradiation to obtain the transparent conductive elastomers. The application has the advantage that the transparent conductive elastomers are high in light transmission and conductivity, excellent in tensile property and bendability and good in environmental stability.

Description

technical field [0001] The invention relates to the field of ionic liquids, in particular, the invention relates to the application of a polymerizable deep eutectic solvent in preparing transparent conductive elastomers. Background technique [0002] Deep eutectic solvents are a subset of ionic liquids. On the basis of inheriting the advantages of ionic liquids such as low vapor pressure, non-aqueous biocompatibility, non-flammability, chemical stability, and high solubility, they also have low cost and low toxicity. , 100% atom utilization and environmental friendliness in the preparation process, and is expected to replace ionic liquids in the future. At present, deep eutectic solvents are mainly used in such aspects as capturing carbon dioxide, dissolving metal oxides, dissolving drugs and purification, catalysts, electrodeposition, material preparation and processing biopolymers. However, there are relatively few reports on polymerizable deep eutectic solvents in the pr...
