Cellulose acetate composites with bamboo cellulose nanofibers: crystallinity preservation during tetrabutylammonium salt-catalyzed surface acetylation

Key Points

• The aim is to modify cellulose nanofibers to enhance their dispersion and mechanical properties while maintaining crystallinity.
• Developed tetrabutylammonium-based salts for cellulose modification
• Utilized TBA 2-maleate for acetylation of nanofibers
• Evaluated the mechanical performance of cellulose acetate composites
• Achieved 46% improvement in mechanical performance
• Preserved crystallinity of cellulose during the modification process
