Whiskers acetylation

More recently, individual chitin nano-whiskers have been prepared from partially deacetylated a-chitin by fibril surface cationization. When CWs with degrees of N-acetylation (DNAc) 0.74—0.70 were mechanically disintegrated in water at pH 3, individualized nano-whiskers with average width and length of 6.2 1.1 and 250 140 nm respectively, were successfully prepared, as reported by Fan et al. [52] the driving force for individualization of CWs is the same as that in...
