Revolutionizing High‐Temperature Electrical Properties of Epoxy Resin via Tailoring Weak Conjugation Rigid Structures (Small 11/2025)

Epoxy Polymers The fundamental components in high-voltage direct-current technology are gas-insulated lines/switchgears, designed to operate in challenging environments such as oceans and deserts. In article number 2407579, Boya Zhang and co-workers present a universal molecular design strategy that combines rigid benzene with functional bridging groups to form a weakly conjugated structure, effectively suppressing the charge transport, offering a promising approach for next-generation epoxy polymers for extreme conditions.
