Polyvinylidene fluoride (PVDF) polymer has seen increased use in industrial, energy harvesting, and sensor applications due to its chemical inertness, durability, flexibility, and, more importantly,
its ferroelectric properties. Decreases in fabrication scale have increased PVDF sensor capabilities dramatically. Nanofibers fabricated by electro spinning provide an increased surface area over that of amorphous thin films, and thus have a greater sensitivity to measurements collected; analysis is required, however, to ascertain changes made in the sensor capabilities as temperatures increase. We have fabricated PVDF nanofibers by an electro-spinning process and annealed the samples at temperatures ranging from 40oC to 100oC. Scanning electron microscopy (SEM) imaging was performed be... view more»
