| Abstract: | Free‐standing flexible composite films of nanocrystalline cadmium sulfide‐impregnated poly(vinylidene fluoride) (nano‐CdS/PVDF) were prepared using a sol–gel technique. The effect of CdS loading, in the PVDF host matrix, on the dielectric properties was studied. An increase in dielectric constant (more than 10 times) was observed in the films when poled under an electric field. The composite films were also characterized using microstructural, Fourier transform infrared spectroscopy and X‐ray photoelectron spectroscopy measurements. © 2015 Society of Chemical Industry |
