“…10 Thus derived rice straw celluloses are in the form of micrometer wide or larger fibers. Although native cellulose is known to consist of a few nanometer wide elementary fibrils and tens of nanometer wide microfibrils, 11,12 mechanical defibrillation of rice straw cellulose into nanofibers was only first reported in 2009.…”

Rice straw cellulose was completely defibrillated via aqueous counter collision (ACC) at a low energy input of 15 kWh/kg, then fractionated by differential centrifugation into four increasing weight fractions of progressively thinner cellulose nanofibrils (CNFs): 6.9% in 80–200 nm, 14.4% in 20–80 nm, 20.3% in 5–20 nm, and 58.4% in less than 5 nm thickness. The 93.1% less than 80 nm or 78.7% less than 20 nm thick CNFs yields were more than double those from wood pulp by other mechanical means but at a lower energy input. The smallest (3.7 nm thick and 5.5 nm wide) CNFs were only a third or less in lateral dimensions than those obatined through ACC processed from wood pulp, bamboo, and microbial cellulose pellicle. The less than 20 nm thick CNFs could self-assemble into continuous submicron (136 nm) wide fibers by freezing and freeze-drying or semitransparent (13–42% optical transmittance) film by ultrafiltration and air-drying with excellent mechanical properties (164 MPa tensile strength, 4 GPa Young’s modulus, and 16% strain at break). ACC defibrillated CNFs retained essentially the same chemical and crystalline structures and thermal stability as the original rice straw cellulose and therefore were much more thermally stable than TEMPO oxidized CNFs and sulfuric acid hydrolyzed cellulose nanocrystals from the same rice straw cellulose.

“…There are several different ways of pretreating the lignocellulosic biomass, and the effect of the pretreatment has been described as a disruption of the cell-wall matrix including the connection between cellulose, hemicellulose and lignin, as well as the depolymerization and solubilization of the hemicellulose polymers (Ibrahim et al, 2013).…”

“…The peak formed at 1633 cm -1 to 1638 cm -1 confirmed the existence of celluloses. Moreover, the band near 1240 cm -1 , corresponded to the axial asymmetric stretching of =C-O-C of ether-, ester-, and phenolic groups (Ibrahim et al 2013), appeared at a very low intensity in the extracted fibers in Fig. 3.…”

“…This peak was assigned mainly to C=O stretching vibration of the carbonyl and acetyl groups in the xylan component of hemicellulose (Ibrahim et al 2013). Other absorption bands of lignin at approximately 1610 cm -1 (Agblevor et al 2007) disappeared in the extracted fibers.…”

The chemical, morphological, physical, and thermal properties of raw materials and single fibers extracted from different morphological parts of windmill palm were examined and comprehensively characterized after an alkali treatment. Leaf sheathes (LS) with the highest cellulose content (52.26%) achieved the most efficient extraction of fibers. Single fibers extracted from the vascular bundles of the windmill palm raw material had a slender shape with a tapering and sealing terminus, with each single fiber possessing a lumen in its cross-section. These windmill palm fibers displayed similar chemical compositions, but they exhibited significant differences in morphological parameters. Leaf blade fibers (LBFs) had the longest length (1240 μm ± 470 μm) and highest aspect ratio (121.39), which presented excellent potential as a reinforced fiber. After the alkali treatment, almost all of the hemicelluloses and lignin were removed, which resulted in increased crystallinity of extracted fibers. Thermogravimetric analysis confirmed LS stability up to 319 °C, which was higher than that of other materials from windmill palm.
