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...
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...
Comparison of Multi layer Formation Between Different Cellulose Nanofibrils and Cationic Polymers The multilayer formation between polyelectrolytes of opposite charge offers possibility for creating new tailored materials. Exchanging one or both compone... Eronen,Laine,Ruokolainen,... - 《Journal of Colloid...
As a reference, micro-sized TEMPO-oxidized wood fibers and cellulose nanofibrils were mixed to form a transparent and hazy film ("blending" method). These results show that hazy transparent films prepared using the "coating" method exhibit superior application performances than films prepared using ...
Here, bio-nanocomposites of TEMPO-oxidized cellulose nanofibrils (TOCNs) reinforced with layered double hydroxides (LDHs) were prepared through an environmentally benign pathway by aqueous dispersion. The results showed that LDHs could be uniformly dispersed in the cellulose nanofibril matrix to form an...
Cellulose microfibrils (CMFs) and cellulose nanofibrils (CNFs) were isolated from hardwood pulp by 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated oxidation, which produced negatively-charged carboxylate groups on their surface. First, these CMFs and CNFs were used to prepare ...
the oxidized cellulose nanofibers suspension loaded with cells is complexed with calcium ions in a pulling process giving rise to the fiber loaded with cells, with dimensions which allow it to handle. The microscopic images showed the success of the proposed method to incorporate the cells into the...
