Cellulose nanofibrils (CNFs), as one of the most abundant renewable nanomaterials, has garnered interest in numerous fields owing to its many any advantages such as good mechanical properties, high surface area and surface tunability. Recently, CNFs have been shown to be a valuable candidate in...
The molecular structure and hydrogen bond types of nanocellulose are very simple, but the properties of the cellulose materials are excellent, which is worth more deep exploration [35]. 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO) oxidized cellulose nanofibers (TOCNs) is a kind of ...

TEMPO‐oxidized cellulose nanofibrilsthermal stabilityImproving 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 ...
2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO) oxidized cellulose nanofibrils were obtained at room temperature and pH 102,5. After the mechanical disintegration in a micro fluidizer (Microfluidics M-110EH-30, Microfluidics Int., USA), 0.5 wt.% aqueous dispersion was obtained after 24...
