Extraction of nanocellulose from sugarcane bagasse and its characterization for potential applications

Abstract

The development of food packaging films from nanocellulose has received attention from researchers. In this study, the chemo-mechanical method has been used to obtain nanocellulose from sugarcane bagasse. The shape and size of the nanocellulose were examined by field emission scanning electron microscopy (FE-SEM) using ImageJ software, and the result was found to be in good agreement with that of dynamic light scattering (DLS) analysis.Various characterizations such as X-ray diffraction (XRD), Fourier transform infrared (FTIR), thermo-gravimetric analysis (TGA), and ultraviolet visible (UV-Vis) spectrometer for the analysis of crystallinity, chemical structure, thermal stability, and optical properties were performed for fibers and nanocelluloses. Moreover, antibacterial evaluation was also carried out using the disc diffusion method with Bacillus and Escherichia coli bacteria. The removal of noncellulosic elements from fibers after treatment and grinding was revealed by FTIR analysis. Furthermore, nanocellulose exhibited not only higher thermal stability and crystallinity but also acceptable antibacterial properties. Based on the results of this study, polymeric films and composites of the presented nanocellulose might be utilized in food packaging, plastic packaging, and container fabrication.

Mechanical properties of cellulose‐based multiscale composites: A review

“…[6] Several studies have been conducted to replace glass fiber with bio/natural fibers. [7][8][9][10] However, it has declined the mechanical properties of hybrid composites. A survey by Ashish kumre [11] on sisal glass fiber reinforced polymer composites concluded that the sisal/glass fiber composite showed lower mechanical properties than the glass fiber control sample composite.…”

Properties and characterization of carrot nanocellulose/starch biopolymer nanocomposites

“…[ 30 ] In addition, high compatibility of starch and NC fillers increases the water resistance of the film, which is a good feature for food packaging. [ 31,32 ] Extraction of NC from natural fibers and its applications as reinforcement in starch‐based biocomposites have been studied by many researchers. Recently, cellulose nanofibers (CNF) extracted from hemp, [ 33 ] wheat straw, [ 34 ] sisal, [ 35 ] aloe vera, [ 36 ] bamboo, [ 11,37,38 ] and banana peel [ 39 ] have been used to improve the mechanical and barrier properties of the starch‐based composites.…”

Effect of alkali surface treatment and compatibilizer agent on tensile and morphological properties of date palm fibers‐based high density polyethylene biocomposites

“…[ 1–6 ] The advanced applications of natural fibers reinforced composites are mostly used in automobile sectors such as door, instrument panels, glove boxes, seat backs, package trays, interior parts, etc. [ 7–9 ]…”

“…[1][2][3][4][5][6] The advanced applications of natural fibers reinforced composites are mostly used in automobile sectors such as door, instrument panels, glove boxes, seat backs, package trays, interior parts, etc. [7][8][9] Date palm fibers (DPF) represent the most interesting natural fiber especially in the Middle East and North African countries, Algeria alone has more than 18.6 million trees, [10,11] and various date palm tree residues can be obtained after cultivation and fruit harvesting such as twigs, leaf stalks, and tree trunks. These agricultural wastes can be used to develop a promising biomaterial based on DPF for reinforcing thermoplastic polymers in various applications such as packaging and automobile components.…”
