“…Natural fibre-based composite materials have broad applications in industrial components, automotive sector, building structures, furniture and packaging that increase the environmental sustainability by contributing to the production of sustainable materials as alternatives to synthetic or man-made fibres [ 36 ]. Biomass from agricultural waste such as oil palm fronds [ 37 ], Tamarindus indica nut [ 38 ], empty fruit bunch (EFB) [ 39 ], coir [ 40 ], straws, husks [ 41 ], sugar palm [ 42 , 43 , 44 , 45 , 46 , 47 ], water hyacinth [ 12 ], and sugarcane bagasse [ 48 , 49 ] are classified as natural plant fibres. This group also includes some fibre crops, such as cotton, ramie, flax, bamboo, kenaf, jute, abaca, sisal, and hemp.…”

Over the last decade, the progressive application of natural fibres in polymer composites has had a major effect in alleviating environmental impacts. Recently, there is a growing interest in the development of green materials in a woven form by utilising natural fibres from lignocellulosic materials for many applications such as structural, non-structural composites, household utilities, automobile parts, aerospace components, flooring, and ballistic materials. Woven materials are one of the most promising materials for substituting or hybridising with synthetic polymeric materials in the production of natural fibre polymer composites (NFPCs). These woven materials are flexible, able to be tailored to the specific needs and have better mechanical properties due to their weaving structures. Seeing that the potential advantages of woven materials in the fabrication of NFPC, this paper presents a detailed review of studies related to woven materials. A variety of factors that influence the properties of the resultant woven NFRC such as yarn characteristics, fabric properties as well as manufacturing parameters were discussed. Past and current research efforts on the development of woven NFPCs from various polymer matrices including polypropylene, polylactic acid, epoxy and polyester and the properties of the resultant composites were also compiled. Last but not least, the applications, challenges, and prospects in the field also were highlighted.

“…By exposing Ni 3 P- x in FF vapor, the characteristic absorption peak for carbonyl bond stretching vibration was found at 1627 cm –1 (Figure ), which was much lower than that of the FF liquid film, and a significant red shift (Δ64 cm –1 ) was observed. This large red shift suggested that there was a strong interaction between Ni 3 P- x and the CO bond of FF, resulting in a deeply polarized CO bond, which revealed that Ni 3 P-400 could strongly activate the CO bond of FF. , It was beneficial to the selective hydrogenation of the carbonyl group of FF over the Ni 3 P- x surface, while it was found that the absorption bands corresponding to the furan ring of FF at 1569, 1473, 1465, 1393, and 1366 cm –1 were almost unchanged when FF vapor was adsorbed on Ni 3 P- x , indicating that the interaction between the Ni 3 P- x surface and the furan ring of FF was very weak. These results suggested that the Ni 3 P- x catalyst could selectively activate the CO bond of FF, which leads to the selective hydrogenation of carbonyl groups in FF molecules to form FOL, while due to the more acid content and stronger acidity, the selectivity of FOL was not satisfactory when Ni 3 P-300 and Ni 3 P-350 were used as catalysts.…”

In the processes of hydrogenation, the accurate control of product distribution is crucial to the high-value conversion of furfural. Herein, Ni3P catalysts were prepared by phase separation synthesis with porous hollow nanospheres and employed as catalysts for the hydrogenation of furfural. Over the Ni3P-400 catalyst, furfural could be transformed completely with 95.6% selectivity toward furfuryl alcohol under 120 °C and 1.6 MPa for 4 h. The deactivation of the Ni3P-400 catalyst was not observed during 8-run recycling tests. Moreover, using other carbonyl compounds derived from biomass as substrates, excellent catalytic performance was also obtained. Such exceptional features make the Ni3P-400 catalyst promising for industrial applications not only in hydrogenation of furfural but also in hydrogenation of other carbonyl substrates.

“…Comparing the two spectra, the most evident difference is that after curing the bands become broader suggesting the formation of polymeric structures, in particular the region at lower wavenumber become almost flat due to the steric hindrance for out of plane C-OH wagging and C-H bending vibrations [ 36 , 37 ]. Further major observations are the decreasing/disappearing of some signals such as those at 1670, 1392, 1018, 929, and 758 cm −1 , which are related to furfural compounds [ 38 , 39 ]. According to these observations, the crosslinking process could be similar to that observed for the polymer with Mimosa extract, involving the bridging through methylene–furanic units [ 40 ].…”

Quebracho Tannin Bio-Based Adhesives for Plywood

et al. 2022

Wood-based products are traditionally bonded with synthetic adhesives. Resources availability and ecological concerns have drawn attention to bio-based sources. The use of tannin-based adhesives for engineered wood products has been known for decades, however, these formulations were hardly used for the gluing of solid wood because their rigidity involved low performance. In this work, a completely bio-based formulation consisting of Quebracho (Schinopsis balancae) extract and furfural is characterized in terms of viscosity, gel time, and FT-IR spectroscopy. Further, the usability as an adhesive for beech (Fagus sylvatica) plywood with regard to press parameters (time and temperature) and its influence on physical (density and thickness) and mechanical properties (modulus of elasticity, modulus of rupture and tensile shear strength) were determined. These polyphenolic adhesives presented non-Newtonian behavior but still good spreading at room temperature as well as evident signs of crosslinking when exposed to 100 °C. Within the press temperature, a range of 125 °C to 140 °C gained suitable results with regard to mechanical properties. The modulus of elasticity of five layered 10 mm beech plywood ranged between 9600 N/mm2 and 11,600 N/mm2, respectively, with 66 N/mm2 to 100 N/mm2 for the modulus of rupture. The dry state tensile shear strength of ~2.2 N/mm2 matched with other tannin-based formulations, but showed delamination after 24 h of water storage. The proposed quebracho tannin-furfural formulation can be a bio-based alternative adhesive for industrial applicability for special plywood products in a dry environment, and it offers new possibilities in terms of recyclability.
