Abstract

Nonwoven fabric composite formulating polycarbonate (PC) and CuPc was fabricated using electrospun (CuPc: 0 to 10 wt%). Spatial presence of CuPc in composites was ascertained by virtue of Fourier-Transform-Infrared-Spectroscopy (FTIR) analysis and its characteristic peak in Small-Angle-X-ray-Scattering (SAXS) spectra. Dielectric and conductivity characteristics were analysed via Broadband-Impedance-Analyser, further dielectric properties induced morphology was inspected using Field-Emission-Scanning-Electron-Microscopy (FESEM). The effect of filler incorporation in matrix lead to a reduction in dielectric values with the least being 1.694 and consequent incremental loss characteristic was 0.1011 at a concentration of 2wt%, which also delivered maximum AC conductivity of (σAC) 1.08 × 10−6 S/cm.
