Aramid nanofibers and poly (vinyl alcohol) nanocomposites for ideal combination of strength and toughness via hydrogen bonding interactions

It remains challengeable for fabricating polymer nanocomposites with combined high strength and toughness. Inspired by spider silk with multiscale hierarchical architectures, we used aramid nanofibers F-3 (ANFs-3) to reinforce poly (vinyl alcohol) (PVA) via hydrogen bonding assembly. The PVA/ANFs nanocomposite films were prepared by a simple solution casting method. Our results showed that the simultaneously significant enhancement in both...
