Green and tough eutectogel from demethylated lignin: bridging renewable biomass and harsh-environment sensing

Key Points

• The research aims to develop a lignin-based eutectogel that performs reliably in harsh conditions.
• Prepared eutectogel through copolymerization of demethylated lignin and deep eutectic solvent.
• Incorporated dodecyl acrylate into the eutectogel synthesis.
• Evaluated the signal output of the eutectogel in various environmental conditions.
• The eutectogel demonstrated high sensitivity and accuracy in signal output.
• Performance proved stable even in harsh environmental conditions.
