PVA/PEDOT coaxial nanofibers with 100, 150, 240 nm in diameter were successfully fabricated by VDP mediated electrospinning method. These coaxial nanofibers have 80 S cm-1 in conductivity. The enhanced sensitivity was exhibited by PVA/PEDOT coaxial nanofiber adopted VDP mediated electrospinning method compared with conventional bulk films. Additionally, PVA/PEDOT nanofiber sensors with reversible and reproducible response have a measurable value to NH3 and HCl vapor concentration as low as 10 ppm and 5 ppm, respectively. Furthermore, this facile methodology could be expanded to allow the fabrication of another coaxial nanofibers. |
