Abstract:
This research fabricated two ultrafine conducive nanofibrous layer. In the first layer polymer and conductive polymer was used and the second layer was a composition of a polymer, conductive polymer and a carbon-base material. In both cases align and randomized mat of conductive nanofibers was fabricated. Conductive poly (3,4-ethylenedioxythiophene)/ polystyrene sulfonate (PEDOT:PSS) nanofibers are electrospun by dissolving a fiber-forming polymer, polyvinyl alcohol (PVA), in an aqueous dispersion of PEDOT:PSS. For nanocomposite layer the effect of addition of reduced geraphene oxide (RGO) was considered. The ultrafine conductive polymer fibers and also conductive nanocomposite fibrous materials were fabricated using an electrospinning process. A fixed collector and a rotating drum was used for random and align nanofibers production, respectively. The resulting fibers were characterized and analyzed with SEM, FTIR, and two-point probe conductivity test. The average diameter of nanofibers measured by ImageJ software indicated that the average fiber diameter for first layer was 100 nm and for nanocomposite layer was about 85 nm. The presence of PEDOT:PSS and also RGO in the nanofibers was confirmed by FT-IR spectroscopy. The conductivity of align and random layers was characterized. The conductivity of align and random layers was characterized. The conductivity of PEDOT:PSS nanofibers is enhanced more by addition of RGO in aqueous dispersion. Results showed that alignment of fibrous materials can be considered as an engineering tools for tunning the conductivity of fibrous materials for many different applications such as supercapcitors, and conductive and transparent materials.
