“…Cellulose before hydrolysis had peaks as amorphous cellulose I, crystalline cellulose II, and crystalline cellulose I at the intensity value of 2θ of 12.2 o ; 20.3 o and 21.8 o , respectively. Then, TaL powder had peaks as amorphous cellulose I, amorphous cellulose II, and crystalline cellulose II at the intensity value of 2θ of 14.9 o ; 16.1 o ; and 22.4 o , respectively [10], [20]. Therefore, cellulose after hydrolysis or cellulose before hydrolysis correspond to cellulose polymorphs I and II.…”

“…Genus Typha is a source of cellulose that is very abundant among five plants that appear in the wetland worldwide [2]. Typha leaves generally consist of 55-60% cellulose, 10-15% hemicellulose, 25-30% lignin, and 5-10% non-cellulosic materials, including wax and ash [10]. Intermolecular and intramolecular hydrogen bonds bind the amorphous phase and crystalline phase of cellulose.…”

The study of preparation and characterization of microcrystalline cellulose from the Lembang / narrowleaf cattail (Typha angustifolia L.) has been carried out. Alkalinization was done to remove lignin and hemicellulose compounds. The bleaching process was done by adding 4 M HCl at 65 oC for 3 hours and then sonicated for 10 minutes. The cellulose yield obtained was 32.2%. The Fourier Transform Infrared (FTIR) spectra indicated the appearance of some specific functional groups (O-H, -C-H, =C-H and C-O, and C-O-C). Scanning Electron Microscope (SEM) showed that the structure of cellulose is a long crystalline with a diameter of 3.1 µm. Thermogravimetric analysis (TGA) showed decomposition at higher temperatures of 349.13, 366.66 and 353.24 oC for cellulose after hydrolysis, cellulose before hydrolysis, and TaL powder. Crystalline index and crystalline size of microcrystalline cellulose analyzed by X-Ray Diffraction (XRD) were 71.1% and 2.4 nm, respectively.

“…Compared to other natural fibers, its potential has been unutilized [2,3]. In several previous studies, Typha angustifolia fiber was found to have several advantages such as excellent bending properties, light weight, excellent mechanical properties, low density, and renewability [4][5][6]. Even though natural fiber has many advantages, many researchers have highlighted the fact that the incompatibility between hydrophilic cellulose and hydrophobic polymer is a crucial weakness of natural fibers.…”

The Role of Typha angustifilia Fiber–Matrix Bonding Parameters on Interfacial Shear Strength Analysis

et al. 2022

The microbond test of natural fibers tends to produce scattered interfacial shear stress (IFSS) values. The sources of this scattering are known, but the roles they play in producing high IFSS scattering remain to be investigated. In this study, a numerical method was used to simulate microbond testing and to examine the experimental parameters in a microbond test of Typha angustifolia fiber/epoxy. Three parameters were considered: fiber diameter, fiber length embedded in the epoxy, and the distance between the vise and the specimen. The geometries were modeled and analyzed by ABAQUS software using its cohesive zone model features. There were two types of contact used in this analysis: tie constraint and surface-to-surface. The results showcased the roles of the following experimental parameters: a larger fiber diameter from a sample increased the IFSS value, a longer embedded length reduced the IFSS value, and a shorter vise–specimen distance increased the IFSS value. The IFSS scattering in the microbond test could have originated from the interaction between these parameters. Of the three parameters, only the vise–specimen distance was found to be able to be reasonably controlled. When the IFSS value was atypically large, fiber diameter and/or embedded length potentially drove the scattering. This study advises further compilation and classification of the role of each experimental parameter in modulating the IFSS value.

Growing awareness of fossil depletion, plastic pollution, and food spoilage has led to the exploration of bioresources as alternatives for producing packaging films for highly perishable food. In this study, we utilized a novel integrated process using natural‐based solvents to isolate cellulose, hemicellulose, and lignin from cattail leaves, an abundant invasive plant. The process yielded cellulose, hemicellulose, and lignin with recovery yields of 96.2 ± 1.2%, 92.5 ± 1.6%, and 94.3 ± 0.7% and purities of 96.3 ± 0.6%, 97.7 ± 0.9%, and 98.9 ± 0.5%, respectively. Spherical nanoparticles (60–90 nm) were synthesized through ultrasonication and their structural purity were confirmed by FTIR, XRD, and XPS analyses. These nanoparticles were incorporated as reinforcement into chitosan (C) films. Cellulose nanoparticles (CNP) and lignin nanoparticles (LNP) significantly enhanced film tensile strength (up to 27% at 1.5% loading), while hemicellulose nanoparticles (HNP) increased film elongation (up to 42%). The complex structures of HNP and LNP promoted higher free radical formation, resulting in enhanced antioxidant activity of up to 80% and 82%, respectively. LNP‐reinforced films exhibited superior antimicrobial properties due to their polyphenolic structure. Preservation tests were conducted by packaging poultry meat in the films and refrigerating it for 30 days. Poultry meat packed in LNP‐reinforced film maintained its quality within permissible limits throughout the entire 30 day period, while LDPE, plain chitosan, C‐CNP, and C‐HNP films reached consumable limits on the 5th, 10th, 15th, and 25th days, respectively. This study highlights the production of sustainable nanoparticles from invasive crops and their application in the development of active packaging films for fresh poultry meat.
