Description
Summary:► For the first time, cellulose nanowhiskers are extracted from TEMPO oxidized jute. ► The dimension of the nanowhiskers is 3–10nm in width and 100–200nm in length. ► Carboxylate groups formed on cellulose nanowhiskers results in a negative charge. ► It is easily dispersed in water and forms stable and transparent suspension. Cellulose nanowhiskers is a kind of renewable and biocompatible nanomaterials evoke much interest because of its versatility in various applications. Here, for the first time, a novel controllable fabrication of cellulose nanowhiskers from jute fibers with a high yield (over 80%) via a 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)/NaBr/NaClO system selective oxidization combined with mechanical homogenization is reported. The versatile jute cellulose nanowhiskers with ultrathin diameters (3–10nm) and high crystallinity (69.72%), contains C6 carboxylate groups converted from C6 primary hydroxyls, which would be particularly useful for applications in the nanocomposites as reinforcing phase, as well as in tissue engineering, pharmaceutical and optical industries as additives.
