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 ...
Nanocellulose constitutes a sustainable and biobased solution both as an efficient sorbent material for water treatment and as support for other inorganic ... Laura Riva,Anna Dotti,Giovanna Iucci,... 被引量: 0发表: 0年 TEMPO-oxidized bacterial cellulose nanofibers-supported gold nanoparticles with ...
TEMPO-oxidized Nanocelluloses: Surface Modification and use as Additives in Cellulosic Nanocomposites The process of TEMPO-mediated oxidation has gained broad usage towards the preparation of highly charged, carboxyl-functionalized polysaccharides. TEMPO-oxidized nanocelluloses (TONc) of high surface charge ...
Amidation and ionic complexation were evaluated as surface modification treatments for TEMPO-oxidized nanocelluloses (TONc), using octadecylamine (ODA) as the modifying compound. Effects of the two treatments on TONc with respect to degree of ODA substitution, surface hydrophobicity, crystalline character...
We demonstrated an example of the convergence of information technology and materials science to achieve innovative developments based on nanocellulose films27. Hybrid films made of TEMPO-oxidized nanocellulose fibers (TOCNF), a film-forming polymer (PVA) as well as crosslinkers (glyoxal, Gx and amm...
TOCNF obtained by TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical)-mediated oxidation of nanocellulose (Saito, Kimura, Nishiyama, & Isogai, 2007) is a new potential biobased nanomaterial. It possess high crystallinity and dispersion in water (Saito et al., 2007) capable of forming ...
Transparent and conductive paper from nanocellulose fibers Here we report on a novel substrate, nanopaper, made of cellulose nanofibrils, an earth abundant material. Compared with regular paper substrates, nanopape... L Hu,G Zheng,Y Jie,... - 《Energy & Environmental Science》 被引量: 159发表...
The development of new cell carrier systems is crucial for application in regenerative medicine, once they deliver the cells to the injured tissue to trigger the repair and stimulate the regeneration. Here we report the preparation of a cell carrier system in fiber shape, in which the cells oste...
2020). Their results showed that the whisker form of nanocellulose (i.e., needle-like cellulose nanocrystals with a diameter of 5–20 nm and a length of 100–400 nm) enhanced the printability of the gel while the fibril form (i.e., flexible cellulose nanofibrils and bacterial nanocellulose...
