Wetting and supercontraction properties of spider-based nanofibers
2019
Spider dragline silk has the highest strength among all natural or artificial
fibers. This paper is to take full advantage of this property to enhance
polyvinyl alcohol nanofibers by adding spider powders in the spun solution
by the electrospinning. The obtained spider-based nanofiber shows much
higher toughness than its polyvinyl alcohol partner. We also find that the
spider-based nanofibers have supercontraction and wetting properties
similar to those in the spider silks. This paper sheds a new light on a new
trend of nanobiomimetics.
