Transparent and high gas barrier films of cellulose nanofibers prepared by TEMPO-mediated oxidation.

abstract：:Cellulose is the most familiar and most abundant strong biopolymer, but the reasons for its outstanding mechanical performance are not well understood. Each glucose unit in a cellulose chain is joined to the next by a covalent C-O-C linkage flanked by two hydrogen bonds. This geometry suggests some form of cooperativi...
