FIG. 1.

AFM phase images of a single electrospun PEO fiber observed at (a) and (b) , showing the change from a solid cylindrical fiber to liquid droplets.

FIG. 2.

Plot of the loading-unloading normal force-indentation depth for the indentation of an electrospun PEO fiber at showing the fitting curve with the theoretical dependence of Eq. (1). is the maximum indentation depth observed by the maximum applied force and was taken at the intersection of the unloading curve and the zero axis. Inset shows the observed unloading curves of this PEO fiber over a range of temperatures from 23 to 40, 50, 55, 58, 60, 61.5, until (left to right), indicating an increased with increasing fiber temperature under similar applied force.

FIG. 3.

Calculated elastic modulus of the PEO fiber and film from the experimental data fit of Eq. (1) as a function of temperature.
