2019/12/15 · Chitin nanocrystals were prepared from the chitin powder following the method as reported previously ( Fan et al., 2008a ). Briefly, TEMPO (0.064 g) and sodium bromide (0.4 g)
Cellulose is the most abundant biomass material in nature. Extracted from natural fibers, its hierarchical and multi-level organization allows different kinds of nanoscaled cellulosic fillers—called cellulose nanocrystals or microfibrillated cellulose (MFC)—to be obtained. Recently, such cellulose nanoparticles have been the focus of an exponentially increasing
