Aromatic polythiourea (ArPTU) is an amorphous, polar, glass‐phase dielectric polymer which features extremely high dielectric breakdown strength (>1.1 GV/m), low loss at high electric fields (10% at 1.1 GV/m), and a high maximum electrical energy density (>24 J/cm 3 ). This work presents a study of the structure–property relationships and electrical conduction in ArPTU, and offers a phenomenological explanation for the experimentally observed high‐field loss characteristics which facilitate the excellent energy storage properties.
