Cellulose, as a high-potential renewable feedstock, holds a significant promise for the development of sustainable thermoplastic, biocomposite and textile materials. (1,2) Esterification of cellulose represents a crucial pathway for converting it into functional materials with desirable properties. (3,4) However, conventional solvent-based modification methods often require large quantities of solvents and high temperatures, posing safety risks and increasing costs. In contrast, mechanochemical modification via ball milling has demonstrated its effectiveness in covalently modifying cellulose with target functional groups while minimizing solvent use and eliminating the need for heating. (5) Building on these advantages, our work focuses on utilizing mechanochemistry to modify cellulose for applications in packaging and as additives in biocomposites.
