Integrated exploration of experimentation and molecular simulation in ester-containing polyimide dielectrics.

ABSTRACT: With the growing development of film capacitors in various applications, the requirements for polymer dielectrics have increased accordingly. In this work, a series of ester-cotaining polyimide (EPI) dielectrics were designed and fabricated. Futhermore, integrated exploration of experimentation and molecular simulation is proposed to achieve polymer dielectrics with advanced comprehensive performance, as well as to analyze the dielectric mechanism in-depth. The EPIs show superior thermal resistance and dielectric properties. A Weibull breakdown strength of 440-540 MV m^-1, permittivity of 3.52-3.85, dissipation factor of 0.627-0.880% and theoretical energy density of 3.13-4.90 J cm^-3 were obtained for the EPIs. The relationship between microscopic parameters and dielec
