Abstract The composites of PVDF and SCF is prepared by solution casting techniques. The composites of 0.0, 0.1, 0.2, 0.5, 1.0, 2.0, and 5.0 phr SCF are prepared with aspect ratio of SCF 147, 294, 441, 588, and 735 (corresponding SCF length 1, 2, 3, 4, and 5 mm). Percolation threshold of composites decreases with increase in SCF aspect ratio. The AC conductivity of each composite is dependent on frequency below percolation threshold and it is independent of frequency above percolation. Some composite exhibit positive temperature coefficient (PTC) and rest negative temperature coefficient (NTC) effect of resistivity. Dielectric constant increases with SCF loading as well as SCF length at particular SCF loading at 1 MHz. Dielectric loss is also affected by SCF loading and its aspect ratio. Optical Microscope (OM) pictures reveal distribution of SCF in PVDF matrix. Keywords: Aspect ratio, PVDF, SCF, Percolation threshold, Dielectric properties
