Abstract

Polyvinyl Chloride nanofibers were fabricated from scrap PVC pipes via the process of electrospinning under a constant voltage of 17 kV. Polyvinyl Chloride (PVC) — Polyaniline (PANT) nanofibers were also fabricated under 17 kV. Tetrahydrofuran was used as solvent with a constant 8g:50m1 ratio for polyvinyl chloride, and N-methyl-2-pyrrolidone was used as solvent with a constant 10g:90m1 for PAM. The PVC-PANT blends used were 90/10, 87/13, 85/15, 80/20, 75/25, 67/33, 50/50 and 33/66. Fourier transform infrared spectroscopy (FTIR) confirmed the presence of unaltered PVC:PAN1 blend, as well as peaks that are attributed to additives in the PVC pipes. Scanning electron micrograph (SEM) revealed the presence of nanofibers. Pixel analysis of SEM images verified the existence of fibers ranging from 76 to 931 nanometers. Pixel analysis also showed that the mean fiber diameter increases as the amount of PANT in the blend increases. Existence of melts and beading were also observed in the SEM images.
