Dielectric relaxation behaviour in semi-crystalline polyvinylidene fluoride (PVDF)/TiO2 nanocomposites

AC and DC electrical conductivity in natural rubber/nanofibrillated cellulose nanocomposites

“…The frequency varied from 0.1 Hz to 1 MHz at an oscillation voltage of 1 V. The measured dielectric permittivity data were collected and evaluated by WinDETA impedance analysis software. According to the planar capacitor rule, the complex dielectric function for the polymer is expressed as [28][29][30][31][32][33]:…”

Ionic hopping conductivity in potential batteries separator based on natural rubber–nanocellulose green nanocomposites

“…According to the planar capacitor rule, the complex dielectric function for the polymer is expressed as [31][32][33][34]: Dielectric measurements were carried out using a Novocontrol concept Alpha-Aanalyzer.…”

Dielectric dispersion and relaxation studies of melt compounded poly(ethylene oxide)/silicon dioxide nanocomposites

“…Our survey of literature revealed that, so far the PEO and SiO 2 interactions and their effect on the polymer physico-chemical properties are characterized by rheological, differential scanning calorimetry (DSC), thermo gravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), dynamical mechanical analysis (DMA), X-ray diffraction (XRD) scanning electron microscopy (SEM) and transmission electron microscopy (TEM) measurements [1,[3][4][5][6][7]19]. Besides these experiments, the dielectric relaxation spectroscopy (DRS) is also a powerful tool for the study of polymer and nanofiller interactions and their effect on polymer dynamics in the PNC materials [20][21][22][23][24][25][26][27][28][29][30][31]. Further, the investigation on dielectric properties of such PNCs can provide the in-depth discussion of nanodielectrics, which is an emerging and fast-moving topic in electrical insulation for microelectronic devices.…”
