Zwitterionic Acetylated Cellulose Nanofibrils.

ABSTRACT: A strategy is devised to synthesize zwitterionic acetylated cellulose nanofibrils (CNF). The strategy included acetylation, periodate oxidation, Schiff base reaction, borohydride reduction, and a quaternary ammonium reaction. Acetylation was performed in glacial acetic acid with a short reaction time of 90 min, yielding, on average, mono-acetylated CNF with hydroxyl groups available for further modification. The products from each step were characterized by FTIR spectroscopy, ?-potential, SEM-EDS, AFM, and titration to track and verify the structural changes along the sequential modification route.
