Cellulose nanocrystal based composites: A review
نویسندگان
چکیده
Cellulose nanocrystals (CNC) have received much attention as renewable, biodegradable, nontoxic, and low-cost nanomaterials with some remarkable properties. Desirable engineering properties of CNC include large surface to volume ratio, high tensile strength (~10 GPa), stiffness (~110–130 flexibility. They can be chemically modified tailor their for high-end biomedical applications. Despite outstanding properties, the wide-scale application is lacking due characteristics processing challenges. To achieve full potential safer extraction methods, improved modification functionalization methods techniques are being researched. This review attempts access characterizing CNC, composites well emerging new applications smart materials. The a valuable resource researchers scientists working in industry or academia provide an update on use materials packaging, biomedical, high-efficiency energy systems.

Spider Silk-CBD-Cellulose Nanocrystal Composites: Mechanism of Assembly
The fabrication of cellulose-spider silk bio-nanocomposites comprised of cellulose nanocrystals (CNCs) and recombinant spider silk protein fused to a cellulose binding domain (CBD) is described. Silk-CBD successfully binds cellulose, and unlike recombinant silk alone, silk-CBD self-assembles into microfibrils even in the absence of CNCs. Silk-CBD-CNC composite sponges and films show changes in ...
متن کاملCellulose nanocrystal reinforced oxidized natural rubber nanocomposites.
Natural rubber (NR) latex particles were oxidized using KMnO4 as oxidant to promote the insertion of hydroxyl groups in the surface polyisoprene chains. Different degrees of oxidation were investigated. Both unoxidized and oxidized NR (ONR) latex were used to prepare nanocomposite films reinforced with cellulose nanocrystals (CNCs) by casting/evaporation. The oxidation of NR was carried out to ...
متن کاملDigital Color in Cellulose Nanocrystal Films
Cellulose nanocrystals (CNCs) form chiral nematic phases in aqueous suspensions that can be preserved upon evaporation of water. The resulting films show an intense directional coloration determined by their microstructure. Here, microreflection experiments correlated with analysis of the helicoidal nanostructure of the films reveal that the iridescent colors and the ordering of the individual ...
