Overview

This work demonstrates lignin extraction using choline chloride and urea in Paulownia, suggesting its potential in DES gel applications.

Key Points

  • To explore the extraction of lignin from Paulownia using deep eutectic solvents and its application in DES gels.
  • Prepared binary and ternary DES systems with choline chloride, lactic acid, glycerol, urea, and acrylic acid.
  • Analyzed the chemical structure and thermal properties of extracted lignin.
  • Investigated the impact of lignin structure on DES gel properties.
  • Lignin extracted retained basic structural characteristics, including the benzene ring.
  • The acidic DES system disrupted β-O-4′ linkages and influenced lignin's molecular weight distribution.
  • Mechanical and thermal properties of DES gels did not show significant differences across various lignin sources.
