Abstract

This letter investigates dielectric responses of aromatic polyurea thin films fabricated through vapor deposition polymerization. The high quality polymer films exhibit high breakdown field (800 MV/m) and high-energy density (>12 J/cm³) at room temperature. These values decrease slightly from room temperature to 180 °C. Linear dielectric responses were found in the films even under high fields and high temperatures with a high charge-discharge efficiency (>90%). These high performance features make aromatic polyurea attractive for high-energy density capacitors, especially under high temperatures.
