FeCl3-catalyzed acetic acid pretreatment for surface-acetylated cellulose nanofibrils enabling Pickering emulsions and tunable optical composite films.
The development of green and sustainable strategies to produce cellulose nanofibrils (CNFs) with tailored surface chemistry for interfacial stabilization and advanced functional composites is of significant importance. In this study, acetylated CNFs were fabricated through FeCl₃-catalyzed acetic acid (AA) pretreatment...
