“…The polarization of dielectric is contributed by dielectric, polar and ionic means [14]. Electronic polarization occurs during very short intervals of time, ionic polarization in the range of a few seconds, whereas the dipole polarization takes relatively longer durations [15]. Polymer nanocomposites are known to possess good barrier, mechanical properties [16], reduced flammability [17], increased heat distortion temperature [18] and reduced solvent uptake [19].…”

“…CuO, as a nanopowder has also been used as a catalyst in adsorption studies for wastewater treatment and for antimicrobial applications [13]. In addition to this, CuO nanoparticles find applications in nanofluids [14]; CuO and Cu 2 O nanospheres are used in sensitive gas sensors [15] and in supercapacitors [16] as well.…”

The objective of this study was to investigate the effects of CuO nanoparticles on the structural, thermal and electrical properties of polyvinyl alcohol (PVA) thin films. The thin films were prepared by a solution casting technique with different weight percentages viz., 0.5, 1.0, 1.5 and 2.0 wt% of CuO nanoparticles in PVA matrix. The fabricated nanocomposite thin films were structurally characterised by Fourier transform infrared spectroscopy and X-ray diffraction, while differential scanning calorimetry indicated the effect of CuO nanoparticles on thermal properties of PVA. The surface morphology of the films was determined by scanning electron microscopy technique. Dielectric properties were analysed using high frequency LCR metre and were found to be dependent on frequency and CuO concentration. Dielectric constant decreased with increase in both frequency and CuO concentration. Dielectric loss increased with frequency increase and decreased with increase in CuO concentration. AC conductivity increased with increase in frequency. PVA-2.0 wt% CuO nanocomposite was found to possess desirable properties such as low dielectric constant and low dielectric loss which makes it a desirable material for use in microelectronics industry.

“…Furthermore, dielectric losses in piezoceramics are practically insignificant (loss factor in a range of 0.002-0.02), whereas the dielectric loss factor of PVDF is ∼0.25 [21]. It has also been reported that dielectric losses in metallized PVDF films sharply increase with lowering frequency [22].…”

We report a flexible energy harvesting circuit fabricated by roll-to-roll compatible, solution-processable methods. The circuit incorporates a supercapacitor fabricated from a viscous carbon nanotube dispersion, printed Schottky diodes, and a piezoelectric element. Used low-temperature materials enabled component integration on poly(ethylene terephthalate) substrate. The supercapacitor was built with a paper separator and an aqueous NaCl electrolyte. Together with carbon-based electrodes, these materials translated into a disposable and environmentally safe electronic device. The energy harvested from mechanical movement was used to drive a commercial electrochromic display.
