AbstractA series of 3D printable multifunctional ionic gels (IGs) are developed incorporating ionic liquid (IL) in the thiol–ene network of thiol‐based end‐crosslinker and acrylate monomers. The resulted gels, termed as thiol‐ionic gels (T‐IGs), are highly transparent and very soft with IL content of 70–85 wt%. The mechanical and conductive properties of the T‐IGs are found to be largely dependent on the IL content, end‐crosslinker functionalities, and chain‐length of monomers. Progression of ionic conductivity is observed with an increase in IL content and conductivity as high as 5.40 mS cm−1is attained for longer acrylate group containing T‐IGs at room temperature, while further increase is observed at elevated temperature. T‐IGs in all systems are found to exhibit superior thermal stability. Three‐dimensional fabrication of these functional T‐IGs is achieved by optical 3D printing process with microscale resolution in facile steps.
