“…48 Also, the second reason was more active epoxy groups on the surface of ESN, which can interact with microbial membrane proteins to a certain extent and destroy the cell structure. 49 However, the most significant antifungal performance was observed in the SM/ESN/BPA@ SN-1 adhesive. After a prolonged storage period of 10 days, only minor mold spots were discernible on its surface, demonstrating the effective suppression of mold growth.…”

From an environmentally sustainable perspective, soybean meal (SM) adhesive presents an ideal alternative to petrochemical-based adhesives. Generally, strength and toughness are mutually exclusive for an adhesive. Hence, the creation of protein-based adhesives with high water-resistant strength of bonding, remarkable toughness, and multifunctionality remains a notable challenge. This study reports a dual hyperbranched siloxane nanocluster cross-linking strategy for creating SM-based adhesives with superior performance. In detail, synthesized hyperbranched epoxy siloxane nanocluster (ESN) and hyperbranched phenylboronic acid siloxane nanocluster (BPA@SN) were introduced into the SM matrix to establish a targeted crosslinking network between epoxy groups and protein chains as well as phenylboronic acid and polysaccharides. Meanwhile, the flexible Si−O segments within the hyperbranched siloxane facilitated energy dissipation, significantly boosting the adhesive toughness. After cross-linking modification, SM/ESN/BPA@SN-1 adhesive demonstrated outstanding dry bonding strength (2.04 ± 0.18 MPa), water-resistant bonding strength (1.12 ± 0.06 MPa), and toughness (18.5 ± 4.02 kJ/m 3 ). Moreover, the adhesive exhibited distinctly improved resistance to mold, thermal stability, and flame retardancy. Therefore, this new strategy of using functional hyperbranched siloxane nanoclusters and SM to design strong, tough, and multifunctional green and sustainable wood-based biomass adhesives provides new ideas for achieving green development.

“…Cross-linking modification is widely recognized as the most effective approach for enhancing the properties of Soy protein adhesives. 147,148 Chemical crosslinkers have the ability to induce numerous covalent interactions with Soy protein, leading to the creation of a stable crosslinking system, thus significantly enhancing the adhesive's wet bonding strength. [149][150][151][152] By leveraging soy protein as matrix and EP resin as crosslinker, one can formulate wood adhesives that are both economically viable and functionally superior.…”

“…SPI was known to possess a high content of hydrophilic groups that significantly affects the strength of adhesives, particularly in terms of wet strength . Additionally, due to the rich nutritional composition of SPI, enhancing the antimicrobial properties of adhesives has become a significant research focus for scholars. − Many researchers lean toward premodifying SPI to improve the strength and antimicrobial properties of adhesives. , While these modifications to SPI yield favorable results, they undoubtedly increase industrial costs and reduce the competitiveness of the product in the market. The prospects for industrial application of modified SPI are, therefore, very limited.…”

To address the challenges associated with formaldehyde emissions in engineered wood adhesives and simultaneously enhance adhesive properties related to water resistance, fire resistance, and mold resistance, a novel environmentally sustainable biomass-based adhesive was formulated. In this work, kraft lignin was carboxymethylated and then blended with the soy protein isolate (SPI)-based adhesive, the dry and wet shear strength of the plywood bonded by the resultant adhesive was enhanced from 1.10 and 0.63 MPa to 1.73 and 1.23 MPa, respectively, resulting in improvements of 157% and 195%. Carboxymethylated lignin (CML) significantly improved the mold resistance and flame-resistance residual rate of the adhesive and decreased the water absorption rate from 190% to 108%. Furthermore, the adhesive exhibits outstanding flame-retardancy, with self-extinguishing capability rendering it suitable for industrial production. In addition, we also evaluated the performances of resulting adhesives cured with different diepoxides and triepoxides, and the comparisons of the adhesive in this work to commercial urea glue and soy protein-based adhesives were conducted. To our delight, the SPI-10CML adhesive presented comparable or even improved performances, showing its promising practical applications such as for fire doors.
