“…[ 46 ] The average crystallite size for cellulose fiber was 1.52 nm in our study whereas this value for the earlier studies was between 4 and 9 nm. [ 25 ] The CrI and average crystallite size for silica were 52.6% and 16.99 nm, respectively. It was reported that the average crystallite size for silica at 800°C was found 44.68 nm.…”

“…The average crystallite size of the dimension perpendicular to lattice plane was determined utilizing the Scherrer Equation [ 25 ] :

L goodbreak= ((), k goodbreak\times λ) / ((), β goodbreak\times \cos θ)

where L is the size of crystallite (nm), k is Scherrer constant (0.9), θ is the Bragg angle in the degrees, β is the line broadening at full width at half maximum (FWHM) in radians, and λ is the X‐ray wavelength (0.154 nm).…”

“…In line with previous literature, CrI for cellulose fiber was ranged between 61% and 74%, which is similar to our study. [25,45] The higher CrI means the proper removal of the amorphous part of the cellulose by breaking the glycosidic bonds during the extraction process. [45] It was claimed that as the crystallinity of the cellulose increases, the mechanical properties of composites improve.…”

Bioplastics are environmental‐friendly materials that have been essentially required to reduce global pollution resulting from the accumulation of conventional plastics. The current study was focused on simultaneous extraction of cellulose fiber and crystal biogenic silica from the same rice husks and preparation of silica‐reinforced cellulose‐based composite bioplastic films via casting method to evaluate in packaging applications. Herein, ZnCl2 was utilized as a solvent for the extracted cellulose fiber for the first time. As the silica content increased, barrier properties of bioplastic films increased. The highest tensile strength value in bioplastic films was obtained at 1347 kN/m2 with 2% weight silica content. The biodegradability of bioplastic films in the soil after 21 days varied between 25.5% and 55.7%, which values were significantly higher than conventional plastics. After evaluating these properties, we strongly believe that composite bioplastic films have a high potential to be utilized as green packaging material.

“…Cellulose, which originates from microbes, algae, and plants, is one of the most important organic molecules on Earth (Divakaran et al 2024a) and is used extensively across numerous industries (Bhandari et al 2020a). Each unit of cellulose has three oxygen atoms and six hydroxyl groups (Bhandari et al 2020b). Cellulose, being the most prevalent polysaccharide globally, is extensively regarded as a sustainable substitute for synthetic plastics over an extended period of time (Tarchoun et al 2019b).…”

Biobased waste utilization is an intriguing area of research and an ecologically conscious approach. Plant‐based materials can be used to render cellulose, which is an eco‐friendly material that can be used in numerous aspects. In the current investigation, cellulose was extracted from the leaves of the Vachellia nilotica plant via acid hydrolysis. The application of this research is specifically directed toward the utilization of undesirable plant sources. To validate the extracted cellulose, FT‐IR spectroscopy was applied. The cellulose was measured to have a density of 1.234 g/cm3. The crystallinity index (58.93%) and crystallinity size (11.56 nm) of cellulose are evaluated using X‐ray diffraction spectroscopy analysis. The highest degradation temperature (320.8°C) was observed using thermogravimetry and differential scanning calorimetry curve analysis. The analysis of particle size was conducted utilizing images captured by scanning electron microscopy. Particle size of less than 30 μm was found and they exhibit non‐uniform orientation. Additionally, atomic force microscopy analysis shows an improved average surface roughness (Ra), which increases the possibility of using extracted cellulose as reinforcement in biofilms.
