Cellulose nanofiber board

Carbohydrate Polymers, 2018
A cellulose nanofiber board (CNF-board) with a nominal thickness of 3 mm was fabricated without adhesive or additive. To provide comparison, a cellulose fiber board (CF-board) was also fabricated. A novel cold pre-press apparatus was made to dewater highly absorbent CNF gel prior to drying.

Cellulose Nanofibers/Polycarbonate Nanocomposite

Materials Science Forum, 2021
In this study, cellulose nanofiber (CNF) was prepared from carrot residues and further surface modification was carried out using suspension polymerization. Subsequently, these CNFs were added to polycarbonate (PC) to prepare a series CNF reinforced nanocomposites.

TEMPO-oxidized cellulose nanofibers

Nanoscale, 2011
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.

Electrospun Cellulose Nitrate Nanofibers

Journal of Nanoscience and Nanotechnology, 2010
Cellulose nitrate nonwoven mats of submicron-sized fibers (100-1200 nm in diameter) were obtained by electrospinning cellulose nitrate solutions. Two solvent systems were evaluated. A 70:30 (wt) ratio of ethanol to acetone and a 60:40 (wt) ratio of tetrahydrofuran (THF) to N,N-dimethylformamide (DMF) were studied. The effects of the two solvent systems,

Glassy carbon nanofibers from electrospun cellulose nanofiber

Journal of Materials Science, 2014
Glassy carbon nanofibers (g-CNFs) with diameter of ca. 45 nm were prepared from electrospun cellulose nanofibers (CelluNFs) by two sequential steps: stabilization and carbonization. The CelluNFs were stabilized at 400 °C and carbonized at 850 and 1400 °C to produce g-CNFs.

Cellulose‐Rich Nanofiber‐Based Functional Nanoarchitectures

Advanced Materials, 2015
Surface self‐assembly of functional molecules or nanoscale building blocks is an effective strategy for the syntheses of advanced materials. Natural cellulose‐rich substances have unique macro‐to‐nano hierarchical structural features. The fabrication of nanoarchitectures, employing specific guest species on the surfaces of the fine structures of such ...

Adjustable film properties of cellulose nanofiber and cellulose nanocrystal composites

Carbohydrate Polymers, 2022
A novel nanocomposite comprised of cellulose nanocrystals (CNCs) and 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO) oxidized cellulose nanofibers (TOCNFs) was prepared through solution casting to evaluate potential improvements of the mechanical performance compared to individual reinforcements alone.

Novel Bioactive Amino‐Functionalized Cellulose Nanofibers

Macromolecular Rapid Communications, 2013
Amino‐cellulose‐based nanofibers are prepared by electrospinning of blended solutions of 6‐deoxy‐6‐trisaminoethyl‐amino (TEAE) cellulose and polyvinyl alcohol (PVA). The TEAE cellulose with a degree of substitution of 0.67 is synthesized via a nucleophilic displacement reaction starting from cellulose‐p‐toluenesulfonic acid ester.

Hydrolytic Activities of Crystalline Cellulose Nanofibers

Biomacromolecules, 2013
Cellulose is commonly believed to be inactive to organic substances; this inertness is an essential requirement for raw materials in industrial products. Here we demonstrate the contradictory but promising properties, which are the hydrolytic activities of crystalline cellulose nanofibers for the ester, monophosphate, and even amide bonds of small ...

Protein depletion with bacterial cellulose nanofibers

Journal of Chromatography B, 2018
In this study, we have reported a novel fabrication technique for human serum albumin (HSA) imprinted composite bacterial cellulose nanofibers (MIP-cBCNFs) used for the depletion of HSA selectively from artificial blood plasma for proteomic applications. Molecular imprinting was achieved by using metal ion coordination interactions of N‑methacryloyl‑(l)
