Preparation and Characterization of Polymerizable Deep Eutectic Solvents Ionic Conductive Elastomers

Abstract

To investigate the influence of different molar ratios of raw materials on the performance of Ionic Conductive Elastomers (ICE) based on Polymerizable Deep Eutectic Solvents (PDES), this study employed a UV-initiated in-situ polymerization method. Polymerizable Deep Eutectic Solvents, synthesized by Choline chloride -acrylic acid with molar ratios of 1:1.7, 1:1.6, and 1:1.5, served as raw materials for the preparation of ionic conductive elastomers. Various modern instruments were employed to analyze and test their properties. The results indicate that as the molar ratio of acrylic acid in the raw materials decreases, the conductivity of the ionic conductive elastomers doubles (reaching 0.838 mS·m-1), but their mechanical properties are somewhat affected. Furthermore, UV testing demonstrates high light transmittance and UV shielding advantages. This suggests that adjusting the performance of ICE by controlling the molar ratio of raw materials can meet the requirements of different applications.
