Abstract

Dielectric constant and loss behaviour of pristine and polarized samples of Poly (p-hydroxybenzoic acid-co-ethylene terephthalate) polymer liquid crystals were studied at continuous temperatures ranging from 20 °C to 250 °C, polarized at potentials 500V and 2000V with high precision d.c. power supply. Dielectric constant appears to be almost linearly dependent in the lower temperature region and is independent in the higher temperature region. Dielectric loss becomes approximately ten times lower at higher temperatures.

Strong induced polarity between Poly(vinylidene fluoride-co-chlorotrifluoroethylene) and α-SiC and its influence on dielectric permittivity and loss of their composites

Journal Article Feng, Yefeng; Gong, Honghong; Xie, Yunchuan; ... - Journal of Applied Physics

Interface polarization and interface zone have been widely utilized to account for the abnormally improved dielectric properties of composites although their formation is rather vague and their influence has never been directly measured. In this work, micro α-SiC was designed as the filler particles incorporated into poly(vinylidenefluoride-co-chlorotrifluoroethylene) with internal double bonds (P(VDF-CTFE-DB)) to construct polymer micro composites through solution casting method. The dielectric constant of the composites is found to be increasing linearly as SiC content increases at lower content and the highest value is obtained as 83 at 100 Hz, which is unusually higher than both pristine polymer (13@100 Hz) andmore »« less

Enhanced dielectric properties due to space charge-induced interfacial polarization in multilayer polymer films

Journal Article Chen, Xinyue; Tseng, Jung-Kai; Treufeld, Imre; ... - Journal of Materials Chemistry C

We report that with the recent advancement of power electronics, polymer film capacitors have become increasingly important. However, the low temperature rating (up to 85 °C) and low energy density (5 J cm^-3 at breakdown) of state-of-the-art biaxially oriented polypropylene (BOPP) films have been limiting factors for advanced power electronics. Based on our recent work, multilayer films (MLFs), which consist of a high energy density polymer [e.g., poly(vinylidene fluoride) (PVDF)] and a high breakdown/low loss polymer [e.g., polycarbonate (PC)], have shown potential to achieve high energy density (13–17 J cm^-3), enhanced breakdown strength, high temperature tolerance, and low loss simultaneously.more »« less

Thermally stimulated polarization currents of pristine poly (p-hydroxybenzoic acid - co - ethylene terephthalate) polymer liquid crystals

Journal Article Yarramaneni, Sridharbabu; Anu, Sharma; Quamara, J. - AIP Conference Proceedings

Thermally stimulated polarization currents (TSPC) of pristine PET/0.8PHB polymer liquid crystals have been studied at various polarizing fields ranging from 38.5 kV/cm to 153.8 kV/cm at continuous temperatures ranging from 20 °C to 250 °C. The charge transport phenomena, responsible mechanisms can be investigated by studying TSP current spectra of these polymer liquid crystals. The TSP current spectra consists of two maxima one at low temperature region and the other at high temperature region and a linear variation in the temperature region from 70°C to 190°C. The relaxation behaviour of this PLC is results from various mechanisms associated with crystalline and amorphousmore » phases.« less

Thermal characterization of polymer blends prepared by reactive blending of PC and PET

Conference Fiorini, M; Marchese, P; Pilati, F

Several Poly(ethylene terephthalate)-Bisphenol A polycarbonate (PC/PET) blends were prepared by reactive blending poly(ethylene terephthalate) and Bisphenol A polycarbonate in a batch mixer in the presence of ester exchange catalysts with different catalytic activity, such as Titanium, Terbium, Cerium, Samarium, Europium and Calcium/Antimony compounds. The catalytic activity and mixing time have been correlated with the extent of ester-carbonate exchange reactions and hence the influence of the PET/PC block copolymers formed during the blending on miscibility has been investigated by differential scanning calorimetry. The results of the thermal characterization showed that blends with a single glass transition temperature can be prepared atmore »« less
Dielectric response of polyethersulphone (PES) polymer irradiated with 145 MeV Ne{sup 6+} ions

Journal Article Ali, S.; Khan, Wasi; Naqvi, A.; ... - AIP Conference Proceedings

Heavy ion irradiation produces modifications in polymers and adapts their electrical, chemical and optical properties in the form of rearrangement of bonding, cross-linking, chain scission and formation of carbon rich clusters. Modification depends on the ion, its energy and fluence and the polymeric material. In the present work, a study of the dielectric response of pristine and heavy ion irradiated Polyethersulphone (PES) polymer film is carried out. 250 {mu}m thick PES films were irradiated to the fluences of 10{sup 12} and 10{sup 13} ions/cm{sup 2} with Ne{sup 6+} ions of 145 MeV energy from Variable Energy Cyclotron Centre, Kolkata Onmore »« less
