“…Figure b illustrates that after curing, the SP adhesive sample exhibited a significant enhancement in the C–N and N–H vibration peak at 1210 cm –1 , accompanied by a reduction in the area of the C–O stretching vibration peak at 1065 cm –1 . These changes suggest the occurrence of an amidation reaction . Additionally, the increased peak area at 1730 cm –1 indicates the generation of carbonyl during the esterification reaction .…”

The wood industry faces challenges in producing eco-friendly, high-performance, and formaldehyde-free adhesives. In this study, carboxylated styrene–butadiene rubber (XSBR) was blended with polyamidoamine–epichlorohydrin (PAE) resin, and a controlled amount of CaCO3 powder was incorporated to create an adhesive with exceptional strength. The resulting three-layer plywood demonstrated remarkable dry and wet shear strengths of 3.09 and 2.36 MPa, respectively, and of 2.27 MPa after boiling water tests, comparable to that of phenolic resins. Additionally, the adhesive exhibited strong adhesion across various materials including glass, metal, etc. This exceptional performance was due to two primary factors: (1) the high-density chemical cross-linking reaction and the physical entanglement between XSBR and PAE; (2) the organic–inorganic hybrid involving metal ion complexation developed by CaCO3, which fostered molecular chain connections and enhanced the adhesive–material interface. These findings offer valuable references for further research in the field of wood adhesives.

“…8 However, SM contains large amounts of hydrophilic groups and abundant nutrients (proteins and polysaccharides), resulting in poor water resistance, low mechanical strength, and short storage life. Several modifications like protein denaturation, 9 chemical cross-linking, 10 biomimetic modification, and nanoenhancement 11 have been investigated to increase the waterproofing of SM glues. Enhancement of cross-link density by adding an epoxy cross-linker is the most common method to address the defects in the SM adhesive.…”

The production of wood-based panels has a significant demand for mechanically strong and flexible biomass adhesives, serving as alternatives to nonrenewable and toxic formaldehyde-based adhesives. Nonetheless, plywood usually exhibits brittle fracture due to the inherent trade-off between rigidity and toughness, and it is susceptible to damage and deformation defects in production applications. Herein, inspired by the microstructure of dragonfly wings and the cross-linking structure of plant cell walls, a soybean meal (SM) adhesive with great strength and toughness was developed. The strategy was combined with a multiple assembly system based on the tannic acid (TA) stripping/modification of molybdenum disulfide (MoS 2 @TA) hybrids, phenylboronic acid/quaternary ammonium doubly functionalized chitosan (QCP), and SM. Motivated by the microstructure of dragonfly wings, MoS 2 @TA was tightly bonded with the SM framework through Schiff base and strong hydrogen bonding to dissipate stress energy through crack deflection, bridging, and immobilization. QCP imitated borate chemistry in plant cell walls to optimize interfacial interactions within the adhesive by borate ester bonds, boron−nitrogen coordination bonds, and electrostatic interactions and dissipate energy through sacrificial bonding. The shear strength and fracture toughness of the SM/QCP/ MoS 2 @TA adhesive were 1.58 MPa and 0.87 J, respectively, which were 409.7% and 866.7% higher than those of the pure SM adhesive. In addition, MoS 2 @TA and QCP gave the adhesive good mildew resistance, durability, weatherability, and fire resistance. This bioinspired design strategy offers a viable and sustainable approach for creating multifunctional strong and tough biobased materials.
