Synthesis of crystalline polyamide for synergistically strengthening anticorrelated mechanical property and high-temperature capacitive energy storage.

ABSTRACT: High-temperature resistant polymer dielectrics present large application potentials in harsh-environment electrostatic capacitors. However, the widely used polymer films including polyimide often suffer poor mechanical strength or energy storage level especially at superimposed bending, electrical and thermal stresses during practical operation, owing to the inherent contradiction in synergistically strengthening both sides, which is a challenging problem that urgently needs to be solved. Here an all-organic synthesis route is exploited to synergistically realize high mechanical strength (378.3 MPa), breakdown strength (682 MV/m), energy density/efficiency (6.06 J/cm³ at η = 90%, the peak value reaches 10.29 J/cm³) at 150 °C in fabricated crystalline polyamide film, w
