“…For instance, Teflon perfluoroalkoxy exhibits a dielectric strength of ∼280 MV/m at 125 °C (8). A dielectric field below 270 MV/m has been reported on PPS at 127 °C (21). The extraordinary breakdown strength of PPEK would enable efficient operation of capacitors at temperatures well beyond 100 °C.…”

The synthesis and characterization of poly(phthalazinone ether ketone) (PPEK) for high-temperature electric energy storage applications is described. It was found that PPEK displayed excellent stability of the dielectric properties over a broad frequency and temperature range. Little change in the breakdown field and discharge time has been observed in PPEK with the increase of temperature up to 190 degrees C. A linear correlation between the AC conductance and the angular frequency implied that the hopping as a dominant conduction process contributed to the dielectric loss. Superior energy densities, remarkable breakdown strengths, and fast discharge speeds have been demonstrated in PPEK at various temperatures.

“…What's more, with temperature rising, its poor breakdown strength decreases rapidly, thus limiting the further improvement of U e . 95 A soluble, glassy state polymer PEKNA was synthesized via Yamazaki phosphorylation polymerization by Xu et al 96 The resulting PEKNA film showed a relatively high ε r of 5.3 and low tan δ of 1% at 1 kHz. Besides, due to its high T g (251 C), the ε r and tan δ of PEKNA showed no significant change with the vary of temperature (up to 200 C) and frequency.…”

Dielectric film capacitors for high‐temperature energy storage applications have shown great potential in modern electronic and electrical systems, such as aircraft, automotive, oil exploration industry, and so on, in which polymers are the preferred materials for dielectric capacitors. This review tries to summarize the recent progress in the field of energy storage based on heat‐resistant all‐organic polymers from the perspective of their operating temperatures. Based on this, a summary of commonly used and latest research on high‐temperature polymers is conducted, and they are classified into different heat‐resistant insulation grades, consequently providing a new perspective for high‐temperature polymers dielectric research, especially on the selection of them under different occasions. Emphasis is placed on the influencing factors of polymer performance and ways to develop high‐temperature polymers. Especially, properties under high temperature including dielectric constant and loss, glass transition temperature, and energy density are summarized, inspiring researchers devoting further efforts in this area. A future prospect in this field is also discussed.

Electrical and paramagnetic properties of poly(pheny1ene sulphide) synthesized by a direct method from benzene and sulphur were investigated. In darkness dc conductivity of the polymer in its pristine state is of the order S/m. Upon doping with iodine it increases by 8 orders of magnitude. For undoped samples the n-type conductivity and for those doped with iodine the p-type conductivity was observed. On the basis of ESR experiments the number of spins and g-value were determined, which for undoped polymer at room temperature are equal to 0.80 * 10" spins/g and 2.0037, respectively. Next, the changes in spin concentration both for the iodine doped samples and these annealed within the temperature range 5 13 -903 K were described. An attempt to discuss the ESR lineshape in a quantitative way was also made. ZUSAMMENFASSUNG:Die elektrischen und paramagnetischen Eigenschaften des durch eine direkte Methode aus Benzol und Schwefel synthetisierten Poly(phenylensu1fid)s wurden untersucht . Die Gleichstromdunkelleitfahigkeit dieses Polymeren im nativen Zustand ist 1O-Io S/m. Sie nimmt wahrend des Dotierens mit Jod um 8 GrdBenordnungen zu. Es wurde fur undotierte Proben n-Typ-und fur die mit Jod dotierten Proben p-Typ-Leitfahigkeit beobachtet. Anhand der ESR-Messungen wurden die Zahl der paramagnetischen Zentren und der g-Faktor bestimmt, die entsprechend gleich 0.80 * IO" Spins/g und 2.0037 fur das undotierte Polymere bei Raumtemperatur betragen. &Iderungen der Spinkonzentration sowohl fur die mit Jod dotierten als auch fur die im Temperaturbereich von 5 13 -903 K getemperten Proben werden dargestellt. Es wird versucht, die Form der ESR-Linien auf eine quantitative Weise zu diskutieren.
