Abstract Cellulose nanofibrils (CNFs) are promising sustainable materials that
can be applied to nanocomposites, as well as medical and life-sciences devices.
However, methods for the preparation of these important materials are energy
intensive because heating and mechanical disintegration are required to produce
cellulose fibers below 100 nm in size. In this study, CNFs were prepared through
the multi-site regioselective oxidation of cellulose with 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) and periodate at room temperature (20–25°C), without
any mechanical-disintegration treatment. Transmission electron microscopy
(TEM) revealed that the CNFs had the average widths of 14.1, 55.4, and 81.9
nm for three different… More >
