Bio-inspired co-deposition strategy of aramid fibers to improve performance of soy protein isolate-based adhesive

Renewable bio-based adhesive fabricated from a novel biopolymer and soy protein

“…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.…”

Effects of Pressure from High‐Pressure Homogenization on the Performance of Soybean Flour Based‐Adhesive

“…[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.…”

Chemical Modifications of Continuous Aramid Fiber for Wood Flour/High-Density-Polyethylene Composites with Improved Interfacial Bonding

“…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 ].…”
