Fabrication of Poly(vinylidene fluoride-trifluoroethylene)/Poly(3,4-ethylenedioxythiophene)-Polystyrene Sulfonate Composite Nanofibers via Electrospinning
Nanofibers of PVF2-TrFE/PEDOT-PSS were fabricated at room temperature using electrospinning with the thinnest fiber having a diameter of similar to 15 nm. This process for generating PVF2-TrFE/PEDOT-PSS composite nanofibers is cheap, fast, and reliable. The presence of conducting PEDOT-PSS assisted in the fabrication of PVF2-TrFE nanofibers at low polymer concentrations in N,N,-dimethylformamide and energy dispersive X-ray spectroscopy confirmed the presence of PEDOT-PSS in the nanofibers. As a fiber mat, they were electrically conducting and used in the fabrication ora Schottky diode, and the diode parameters were calculated assuming the standard thermionic emission model of a Schottky junction. Being a composite. these nanofibers are promising candidates for use in a variety of applications that can take advantage of the ferroelectric and/or conducting properties of each individual component. In addition, the large aspect ratio and even larger surface to volume ratio of the fibers makes them ideal candidates in the fabrication of miniaturized, low power consumption devices, and Supersensitive Sensors.
