“…In addition, the peak intensities at 2929, 2854, and 1461 cm À1 increased, the broad band at 1072 cm À1 (C-O-C) disappeared and a new peak attributed to saturated aliphatic ether at 1109 cm À1 occurred, implying that the crosslinker EHL-ESO was introduced. 47,49 On the other hand, the intensity reduction of the peak at 3303 cm À1 (-OH and N-H) was contributed to a hydrogen bonding interaction between EHLA and SPI matrix. Moreover, the peaks at 1164 cm À1 (ester -CO) and 1741 cm À1 (C]O in COOH or COOR) appeared, and the absorption peak at 1386 cm À1 (COO-) was weakened, owing to an esterication reaction between epoxy groups in EHL-ESO and carbonyl groups/carboxyl group in SPI.…”

“…[5][6][7][8] Proteins-especially soybean protein-are renewable, inexpensive, and abundant adhesive materials. [9][10][11] However, soybean flour (SF)-based adhesives always show a low adhesion stability, weak bonding strength, and inferior moisture resistance, preventing their uses in plywood production. [12,13] The low reactivity of SF has always been considered as the main cause of the poor adhesion performance.…”

A green and sustainable soybean flour (SF) adhesive is considered as a potential alternative to toxic formaldehyde‐based resins. Nevertheless, poor bond stability and low bonding strength is caused by the uneven size distribution and low reactivity of SF. Herein, SF adhesives with excellent and stable performance are synthesized via the synergistic action of high‐pressure homogenization (HPH) treatment by incorporating a green crosslinker. Specifically, an even distribution of the SF particles is obtained after the HPH treatment, from which large soy protein molecules are broken to several small and even single protein molecules. In this way, the adhesion stability is improved. Additionally, more active groups buried in proteins are exposed after the HPH treatment due to the unfolding of the protein molecules. Therefore, a more reactive SF is obtained and thus forms a denser crosslinking structure of resultant the adhesive, providing an increase in bonding strength. Particularly, the effects of homogenizing pressure on the adhesive performance are investigated. The results show that a 215.6% increase of wet bonding strength (1.01 MPa) is obtained after the HPH treatment with a homogenizing pressure of 20 MPa, meeting the standards (GB/T 9846‐2015) for interior applications.

“…Inspired by the mussel, dopamine (DPA) was found can deposit a thin polymer film on almost any substrate through oxidative and self-polymerization [ 28 ]. DPA polymer is readily constructed on most substrates without any complex chemical method, so also used as a versatile and effective surface modifier for synthetic fibers (carbon, glass, and aramid fibers) [ 29 , 30 , 31 ]. Additionally, the deposited poly (dopamine) layer contains many –OH and –NH groups, which can be used for further functionalization [ 32 , 33 ].…”

“…Additionally, the deposited poly (dopamine) layer contains many –OH and –NH groups, which can be used for further functionalization [ 32 , 33 ]. Modification by DPA has been proved for improving the compatibility and performance of fiber reinforced composites [ 29 , 34 , 35 ]. Meta-aramid (MPIA) fiber was first modified by dopamine and further grafted silane KH560 by Sa and the interfacial strength between modified aramid fibers with rubber matrix increased by 62.5% [ 32 ].…”

To expand the use of wood plastic composites in the structural and engineering constructions applications, continuous aramid fiber (CAF) with nondestructive modification was incorporated as reinforcement material into wood-flour and high-density-polyethylene composites (WPC) by extrusion method with a special die. CAF was treated with dopamine (DPA), vinyl triethoxysilane (VTES), and DPA/VTES, respectively. The effects of these modifications on compatibility between CAF and WPCs and the properties of the resulting composites were explored. The results showed that compared with the original CAF, the adhesion strength of DPA and VTES combined modified CAF and WPCs increased by 143%. Meanwhile, compared with pure WPCs, CAF after modification increased the tensile strength, tensile modulus, and impact strength of the resulting composites by 198, 92, and 283%, respectively.
