In this article, TEMPO-oxidized cellulose nanofiber (TEMPO-CNF) prepared from bagasse was described and utilized as a sustainable material for the preparation of new nanocomposites. TiO 2 nanoparticles were synthesized by in situ precipitation in the presence of TEMPO-CNF. The prepared nanocomposite,...
Native wood celluloses can be converted to individual nanofibers 3–4 nm wide that are at least several microns in length, i.e. with aspect ratios >100, by TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical)-mediated oxidation and successive mild disintegration in water. Preparation methods...
Cellulose nanofibers membrane not only provides abundant ion transport channels, but also has the density of functionalized molecules in the pore, making ion transport more controllable and effective. Therefore, the construction of membrane materials with cellulose nanofibers can promote the development of...
The width of the isolated CNFs is in the range of 15 nm to 20 nm and the length of cellulose nanofibers is around 1000 nm. The HW-CNF offers better transmittance than the SW-CNF. High transmittance of CNF films from both SWCNF and HW-CNF was observed. In addition, the birefringence ...
In this study, ultralight and hydrophobic carbon aerogels were prepared from 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO)-oxidized cellulose nanofibers (TOCN) for the removal of organic solvents. The morphological structure, density and chemical composition of TOCN aerogels frozen at 56 °C and ...
Electric field alignment of nanofibrillated cellulose (NFC) in silicone oil: impact on electrical properties. This work aims to study how the magnitude, frequency, and duration of an AC electric field affect the orientation of two kinds of nanofibrillated cellulose... A Kadimi,K Benhamou,Z Oun...
Improving thermal stability of TEMPO-oxidized cellulose nanofibrils (TOCNs) is a major challenge for the development and preparation of new nanocomposites. However, thermal degradation of TOCNs occurs at 220 掳C. The present study reports a simple way to improve thermal stability of TOCNs by the...
Surface modification of bacterial cellulose nanofibers for property enhancement of optically transparent composites: Dependence on acetyl-group DS Bacterial cellulose (BC) nanofibers were acetylated to enhance the properties of optically transparent composites of acrylic resin reinforced with the nano...
