Ion–microgel chelation-driven granular eutectogel elastomer with recoverable and anti-fatigue properties

open access: yesResults in Engineering
An unconventional granular eutectogel elastomer was developed by integrating Carbopol microgels into a type IV deep eutectic solvent (DES) composed of CaCl₂·6H₂O and glycerol. Unlike conventional polymer–DES systems, the dispersed microgels assemble into
