“…It was observed that the impurities were reduced after the treatment. This is consistent with other silane-modified natural fibers studies [26]. The analysis of SEM images allows for the assumption that silane treatment was a very helpful method for removal of lignin and hemicelluloses from natural fibers.…”

The study investigated the effectiveness of the combination of chemical and physical methods of natural fibers’ modification. The long flax fibers were subjected to various types of modification. These were silanization, plasma modification and a combination of these methods. For the silanization process, two types of silanes were used: amino- and vinylsilane. The application of structurally different compounds allowed us to acquire knowledge about the effect of the modifier structure on its properties. Various properties of flax fibers were investigated, comparing the results before and after different modification processes. The flammability of prepared samples were tested by pyrolysis combustion flow calorimeter (PCFC). In the effect of the natural fibers’ modifications, flammability was reduced even by 30%. The thermal stability of modified fibers increased. The FTIR tests of the gases released during thermal degradation of the tested fibers allowed us to determine the important compounds and prove a lower degree of flax-fiber decomposition after modification. Flax fibers were also tested to evaluate their physical properties (linear mass, average diameter, aspect ratio and hygroscopicity). Changes in surface morphology were observed by scanning electron microscope (SEM). The properties of natural fibers improved significantly, thus contributing to an increase in their suitability for the use in composites.

“…The specific temperatures (T onset , T 10 , T 60 ) were much higher than those for unmodified fibers as well as DTG peak was slightly shifted to higher temperatures. Numerous studies reported that unmodified fibers had lower decomposition temperature compared to modified fibers [25][26][27][28].…”

“…The second step occurred between 150°C and 250°C and the initial degradation temperature (T onset ) occurred around 220°C, which can be related to decomposition of low molecular weight lignin and others macromolecules, as has been reported by Najeeb et al. (2020) for Malaysian Yankee pineapple leaf fiber. The third step occurred between 250°C and 700°C and the peak temperature (T peak ) occurred at ~280°C.…”

“…This technique enables the correlation of spectral bands of functional groups to chemical substances according to the literature. A broad band at 3,395 cm –1 and 1,642 cm –1 can be related to stretching vibrations of −OH groups in hydrogen bonds of cellulose and water (Najeeb et al., 2020; Olsson & Salmén, 2004). The band at 2,928 cm –1 may be related to bending of CH 2 in hemicellulose (Najeeb et al., 2020).…”

The aim of this study was to obtain and characterize a lyophilized leaf powder from Acmella oleracea (LPA) as a functional food ingredient. Sorption isotherms of LPA display a monolayer moisture content of 9.1 and 9.3 g H2O 100 g–1 for adsorption and desorption, respectively. The flavonoids, ascorbic acid, and total polyphenols content, were approximately 235 mg 100 g–1, 18 mg 100 g–1, and 2,480 mg GAE 100 g–1, respectively. The antioxidant activity by TEAC showed the greatest value, ~291 mg TE L–1, against DPPH and FRAP assays (p < .05). The FTIR spectrum revealed high intensity bands at 3,400 cm–1 related to vibrations of cellulose and organic acids. The thermo‐behavior showed an initial degradation temperature at 222°C and peak temperature of 278°C. These results indicate great potential of LPA as a natural source of bioactive compounds, which could contribute to its utilization as a functional ingredient in foods. Practical applications The lyophilized leaf powder from Acmella oleracea as a natural source of bioactive compounds could contribute to its utilization as a functional ingredient in foods.

Researchers are actively working on developing a long‐term substitute for harmful manmade fibres. Because of their unique qualities that fit diverse applications, natural fibres/fillers are proposed as sustainable reinforcements. Integrating natural fibres, such as Corchorus olitorius particles, into composites provides an environmentally conscious choice for a variety of purposes. This research aims to investigate the influence of silanization, a surface modification technique, on the various characterizations and characteristics of Corchorus olitorius particle‐based composites. The characterizations included morphological, mechanical and thermal investigations to assess the influence of silanization on the characteristics of the composite. The contact layup process is applied to create composite samples by reinforcing multiple weight proportions of treated particles (2.5%, 5%, 7.5%, 10% and 12.5%) in epoxy resins. The findings demonstrate that silanization elevates the interfacial connectivity between Corchorus olitorius particles and the resins, which produces upgraded mechanical and thermal attributes. The composite containing 5 wt% particles generated the most significant tensile and flexural strength, with gains of about 45% and 31%, respectively, compared to the epoxy composite. Because of the higher interfacial connections of the molecules, the viscoelastic features of the composites indicated that the 7.5 wt% particle‐based composite possesses the greatest storage modulus (2.96 GPa), loss modulus (0.4 GPa) and glass transition temperature (90 °C). This study emphasizes the significance of surface alteration procedures such as silanization for boosting the efficiency and long‐term viability of composites containing Corchorus olitorius particles. © 2023 Society of Industrial Chemistry.
