“…The DSC thermogram shows three main peaks: two exothermic straight peaks and one endothermic peak. The endothermic peak is observed at around 68˚C and corresponds to dehumidification of the fiber [39]. The exothermic peaks are observed around 320˚C and 340˚C for the first and around 400˚C and 410˚C for the second.…”

In this research work, fiber extracted from the bark of Cola lepidota (CL) plant, grown in the flora of Southern part of Cameroon, was investigated for composites reinforcement. The investigation was carried via evaluation of water absorption capacity, moisture content, real density, porosity, chemical composition, chemical structure and thermal behaviour. It was discovered that the new fiber has relatively low moisture content and water absorption capacity similar to those of other investigated natural fibers such as flax, sisal, coconut, hemp and jute. Its porosity was found appropriate for composite production and the fiber was found to be thermally stable up to 230˚C, with maximum degradation temperature of 325˚C. The main constituents of the fibre include cellulose, hemicellulose and lignin. In conclusion, based on the properties investigated, this fiber is considered suitable for composite manufacture.

“…The drop-in lignin content after the treatment is a positive effect which indicates the detachment of individual fibers from fiber bundle. [40] Reduced wax content (0.10 wt%) was noted in SAtreated fibers than others which promotes the superior bonding between polymers and fiber while manufacturing the composites. Treated fibers exhibited lowest moisture and ash content compared to UT fiber which improves its dimensional stability, structural properties, firefighting capability, and thermal stability.…”

First time, this study reports the effect of benzoyl chloride (BC), potassium permanganate (PP), and stearic acid (SA) treatments on the surface morphology, physical, chemical, structural, mechanical, and thermal properties of cellulosic fiber obtained from date palm plant petioles. Morphology analysis displayed the existence of protrusions on treated fiber surface, which stimulates the mechanical interlocking between the fiber and polymer matrix. Highest cellulose (67.22%) and lowest hemicellulose (9.25%), lignin (14.02%), ash (3.25%), wax (0.10%), and moisture (8.93%) content were observed in SA-treated fibers than others. Similarly, highest weight loss (20.80%), reduced diameter (0.3166 mm), and density (0.389 g/cc) were obtained in SA-treated fibers than the other fibers investigated. Outcomes of FT-IR spectra evident the presence of cellulose and partial removal of non-cellulosic constituents in BC-, PP-, and SA-treated fibers.Enhanced crystallinity index (69.5%) and crystallite size (7.43 nm) values of SAtreated fiber indicated the elimination of amorphous lignin and hemicellulose, and made the structure to be more crystalline which supports to obtain higher tensile properties (tensile strength of 489.07 MPa and tensile modulus of 9.4 GPa) than others. Maximal degradation temperature of SA-treated fiber was 328.86 C and also having kinetic activation energy of 90.7 kJ/mol.

“…However, the fraction of the amorphic (lignin, hemicellulose, wax) and crystalline (cellulose) in natural fibres might differ with the location and the condition of the grown plant [50]. The fraction of amorphic content in the fibre influences the properties of the materials, so it is necessary to decrease the amorphic fraction in the natural raw fibres before utilizing them as reinforcements [51].…”

This study was driven by the stringent environmental legislation concerning the consumption and utilization of eco-friendly materials. Within this context, this paper aimed to examine the characteristics of starch and fibres from the Dioscorea hispida tuber plant to explore their potential as renewable materials. The extraction of the Dioscorea hispida starch and Dioscorea hispida fibres was carried out and the chemical composition, physical, thermal, morphological properties, and crystallinity were studied. The chemical composition investigations revealed that the Dioscorea hispida starch (DHS) has a low moisture t (9.45%) and starch content (37.62%) compared to cassava, corn, sugar palm, and arrowroot starches. Meanwhile, the Dioscorea hispida fibres (DHF) are significantly low in hemicellulose (4.36%), cellulose (5.63%), and lignin (2.79%) compared to cassava, corn hull and sugar palm. In this investigation the chemical, physical, morphological and thermal properties of the Dioscorea hispida fibre and Dioscorea hispida starch were examined by chemical composition investigation, scanning electron microscopy (SEM), particle size distribution, thermogravimetric analysis (TGA), X‑ray powder diffraction (XRD), and Fourier transform infrared (FTIR), respectively. It was found that Dioscorea hispida waste is promising alternative biomass and sustainable material with excellent potential as a renewable filler material for food packaging applications.
