• Lignin is second most abundant bio-derived material on Earth after cellulose.
• Despite this fact, lignin has been underutilized and treated as a waste after
extraction of cellulose for pulping processes.
• Complicated chemical structure is also a limiting factor of study on lignin.

This project investigates how chemically bonding lignin and PLA together through graft-copolymerization help lignin meet the requirement of fibre spinning material, and how stereocomplex formation of PDLA and PLLA graft copolymers improves thermal and physical properties.
