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

Here, inspired by the adhesion of marine mussels and ascidians, surfacemodified aramid fiber (AF) with a high surface roughness and grafting degree was successfully developed by the catechol/polyamine (CAPA) and pyrogallol/polyamine (PGPA) co-deposition, and then used as a reinforcing agent to improve the performance of SPI-based adhesives.

本研究受海洋贻贝与被囊类动物的粘附机制启发，通过儿茶酚/多胺（CAPA）与焦没食子酚/多胺（PGPA）共沉积法，成功制备出兼具高表面粗糙度与接枝率的表面改性芳纶纤维（AF），并将其作为补强剂，用以提升大豆分离蛋白（SPI）基胶粘剂的综合性能。
