Abstract: | We study the stress–strain behaviors of the electrospun sPP single nanofibers as well as nonwoven mats, which were electrospun
from sPP solutions using two different solvents (decalin and cyclohexane) by electrospinning. The effects of organic solvents
were explored on the morphologies and the mechanical properties of the corresponding electrospun sPP single nanofibers and
nonwoven mats. It was found that the nature of organic solvents dramatically affected the surface morphologies, the circular
and looping deposition of the electrospun sPP fibers, and the mechanical properties. The tensile strength of both electrospun
sPP single nanofibers and nonwoven mats prepared from decalin-base solution was stronger than that of cyclohexane-base solution. |
