“…The peaks at 3400 and 2900 cm −1 in the spectra of all samples correspond to OH stretching vibration of hydrogen‐bound hydroxyl groups and the CH stretching vibration of alkyl groups, respectively. The peak at 1640 cm −1 in the spectra of all samples results from the bending vibration of water absorbed by hydrophilic groups . The peak at 1730 cm −1 only in the FTIR spectrum of RSCB is attributed to the CO stretching vibration of the acetyl and uronic ester groups from hemicellulose or the ester linkage of carboxylic group of ferulic and p‐coumaric acids of lignin and/or hemicellulose.…”

The cellulose fiber was extracted from the abandoned crop sugarcane bagasse (SCB) by means of chemical treatment methods. Poly(lactic acid) (PLA) bio‐based composites with SCB were prepared through fused deposition modeling (FDM) 3D‐printing technology, and the morphologies, mechanical properties, crystallization properties, and thermal stability of 3D‐printed composites were investigated. Compared with the neat PLA, the incorporation of SCB into PLA reduces the tensile strength and flexural strength of 3D‐printed samples but increases the flexural modulus. The difference in tensile performance and bending performance is that the tensile strength of 3D‐printed samples is best when the SCB content is 6 wt%, while the flexural modulus continuously decreases as the SCB content increases. Furthermore, the effects of various printing methods on the tensile performance of 3D‐printed samples were explored via modifying G‐code of 3D models. The results indicate that the optimum SCB fiber content is identical for all printing methods except method “vertical.” Due to the fibers and molecular chains are oriented to varying degrees with altering raster angle in 3D‐printed samples, the fully oriented sample printed by method “parallel” has a better tensile strength. Besides, SCB exhibits enough high thermal decomposition temperature to meet requirements for melt extrusion processing of PLA composites, and SCB fiber is capable of promoting the crystallization of PLA.

“…Traditionally, the cellulose pulp is pretreated by dilute base or dilute acid [158,[186][187][188][189]. For instance, bleached kraft bagasse pulp was pretreated with the aqueous solution of 5% NaOH at 50 ∘ C for 45 min so as to get rid of the residual hemicellulose and lignin and then was further ground to obtain the CNFs [158].…”

“…The process of 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) radical oxidizing the primary alcohol groups of monosaccharides to carboxylic groups was reported by Davis and Flitsch in 1993 which has become one of the most extensive research topics in the area of oxidation of cellulose [202]. The typical oxidation system for cellulose is TEMPO/NaBr/NaClO [203], which has been extensively used for the pretreatment of raw cellulose materials before mechanical disintegration [22,189,204,205]. The mechanism of oxidation reaction is shown in Figure 11 [86].…”

The recent strategies in preparation of cellulose nanocrystals (CNCs) and cellulose nanofibrils (CNFs) were described. CNCs and CNFs are two types of nanocelluloses (NCs), and they possess various superior properties, such as large specific surface area, high tensile strength and stiffness, low density, and low thermal expansion coefficient. Due to various applications in biomedical engineering, food, sensor, packaging, and so on, there are many studies conducted on CNCs and CNFs. In this review, various methods of preparation of CNCs and CNFs are summarized, including mechanical, chemical, and biological methods. The methods of pretreatment of cellulose are described in view of the benefits to fibrillation.

“…Oil palm empty fruit bunches (OPEFB)is by-product of steam sterilization process of oil palm plantations (PKS) (Or, Putra and Selamat, 2017), which can be used as a source of cellulosic fibers., while cellulose nanofibers or cellulose nanofibrils (CNFs) are obtained from OPEFB (Ferrer et al, 2012), which has at least one dimension in nanometer range and low thermal expansion, high specific area, good mechanical, optical properties are had them (Feng et al, 2018), obtained from the steam explosive method. Steam explosive method in alkali medium followed by hydrochloric acid treatment and high shear homogenization is an effective method to be used in the separation of cellulose nanofiber from lignin and hemicellulose (Saelee et al, 2016), (Kaushik and Singh, 2011).…”

This research implemented a green route to multifunctional nanocomposite materials composed by cellulose nanofiber (CNF) and graphene oxide (GO). Aqueous solutions with different ratio of GO (prepared with LiCl/DMAc 8%(w / v)) were mixed with cellulose nanofiber by using magnetic stirrer at the temperature of 70 o C for 30 minutes. The mixture obtained was dried in room temperature for 24 hours. The nanocomposite were characterized with several analysis such as; Fourier Transform Infrared (FTIR), mechanical properties testing, Transmission Electron Microscope (TEM), and Scanning Electron Microscope (SEM) analysis. The characteristic of cellulose nanofiber functional groups was exhibited through FTIR spectra. The CNF/GO with 0.06wt% indicated a higher mechanical properties compared to the CNF. Its tensile strength increased drastically from 26.36 MPa to 49.69 MPa while its young's modulus also showed an extreme increase from 1.379381 GPa to 6.973478 GPa respectively. Moreover, cellulose nanofiber diameter had been examined through TEM and its morphology was analyzed with SEM. Finally, it can be concluded that the celulose nanofiber mechanical properties can be optimized by graphene oxide through the mixing process.
