ABSTRACTPoly(chloro-p- Xylene) or Parylene –C thin films are particularly attractive for dielectric as well as biomedical applications. In the current work the dielectric properties of Parylene-C thin films are investigated to form laminar composites with oxide thin films for high energy density pulsed power capacitors. Parylene-C thin films were synthesized by pyrolytic vapor decomposition polymerization of dichloro-di(p-Xylene) monomer. Annealing of films at 225°C has shown to enhance crystallinity of film. Conduction in Parylene-C thin films appears to be bulk-controlled with the hopping charges contributing to leakage current. The barrier height of 0.89eV and hopping distance of 2 - 2.5nm are physically plausible and similar to previously reported values in polymer literature.

Abstract In this work, lead-free (1-x)(Bi0.5Na0.5)0.94Ba0.06TiO3-xBi(Mg0.5Ti0.5)O3 (abbreviated as BNBT-xBMT, x = 0.3, 0.4, 0.5 and 0.6) thin films were prepared on Pt/Ti/SiO2/Si substrates using sol-gel method. The microstructures, dielectric and energy storage properties were investigated. The results showed that the addition of BMT disrupted the long-range ferroelectric order and enhanced the relaxor behavior of BNBT-xBMT thin films. In addition, the leakage current density of thin films was also reduced by the doping of moderate amount of BMT. A high recoverable energy density of 34.36 J/cm3 with an efficiency of 56.63% was achieved in the BNBT-0.5BMT thin film under the electric field of 2149 kV/cm. Furthermore, BNBT-0.5BMT thin film exhibited superior stability in the temperature range of 30°C − 145°C and frequency range of 500 Hz − 5 kHz, as well as long-term fatigue durability after 1 × 105 cycles. These results suggest that BNBT-0.5BMT thin film may be a promising material for lead-free dielectric energy storage applications.
