| Popis: | Nanofibers of PVF2−TrFE/PEDOT−PSS were fabricated at room temperature using electrospinning with the thinnest fiber having a diameter of ∼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 of a 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 ... |
