Aromatic poly(arylene ether urea) with high dipole moment for high thermal stability and high energy density capacitors

Developing dielectric polymers with higher dielectric constant without sacrificing loss and thermal stability is of great importance for next generation of high energy density capacitors. We show here that by replacing the CH2 group in the aromatic polyurea (ArPU) with the polar ether group, thus ra...
