In Situ Growth of PDA Layer on PEI Film: Enhanced Dielectric Energy Storage Performance and Its High‐Temperature Limitation

ABSTRACT To improve the insulation and energy‐storage performance of polyetherimide (PEI) films, surface‐modified PEI/polydopamine (PDA) films were fabricated via in situ polymerization of dopamine. This study explores the influence of the PDA layer on the wide‐temperature dielec...
