Polymer dielectrics with outstanding heat resistance and advanced dielectric properties are of great importance for hightemperature capacitors in the applications of hostile circumstances. In this work, a series of aromatic carbonyl-containing polyimides (CPI) are prepared from the carbonyl dianhydride and different diamines. The correlation between molecular structure (i.e., different linked structure ( O , CH2 , SO2 ) in diamines, the length of repeating unit and the linked position (para-para or meta-meta), and properties is revealed in detail to obtain CPI dielectrics with excellent thermal resistance (glass transition temperature, T g : 241~352 C), reasonably high dielectric constant (3.99~5.23), low dissipation factor (0.00307~0.00395), and admirable breakdown strength (425~552 MV/m) simultaneously. Particularly, CPI-5 with carbonyl structure in dianhydride and sulfonyl group in diamine proves to exhibit discharged energy density and charge-discharge efficiency of 6.34 J/cm 3 and 92.3% at 500 MV/m, respectively. In addition, CPI-5 also displays stable dielectric properties in temperature range of −50-200 C.

“…Yuan et al . investigated a family of isotactic polypropylene copolymers with various side‐chain groups, and the PPOH (having 4.2 mol % OH content) based thin film capacitor displayed a linear reversible charge storage capacity with high releasing energy density > 7 J cm −3 at an applied electric field of 600 MV m −1 . Another route is to introduce conductive or polar nanofillers forming PP‐based nanocomposites.…”

Maleic anhydride‐grafted polypropylene (MA‐g‐PP) was hybridized with pure PP to form hybrid films with the aim to enhance the dielectric performances of the PP film via polarity adjustment. The changes of microstructure and crystallinity of PP matrix by MA‐g‐PP incorporation were studied, and the polarity change was identified by the surface wettability. The dielectric behaviors of the hybrid films were explored. Increasing polarity of PP film leads to increase in dielectric constant but decrease in breakdown strength, and a balance is achieved in 10 vol % MA‐g‐PP/PP hybrid film, with the maximum discharge energy density reaching 1.96 J cm−3 and charge–discharge efficiency as high as 96%. The ultralow loss is attributed to the dense and homogeneous microstructure together with increased crystallinity induced by incorporation of MA‐g‐PP. These PP‐based films with increased polarity not only show enhanced dielectric performances but also provide a type of matrix that would be compatible with polar fillers to further increase dielectric properties. © 2017 Wiley Periodicals, Inc.

“…High energy storage density capacitors have received broad interest because of their great potential for advanced electronic devices and pulsed power applications [1][2][3][4][5][6][7][8][9]. In general, the energy storage density U of capacitors is expressed as U ¼ R EdD, where E and D are the breakdown strength and electric displacement, respectively [10,11].…”
