Description
Summary:Back Cover: In article number 2100700 by Yang Feng, Shengtao Li, and co‐workers, a new amphiphilic block copolymer with clear phase separation shows an extraordinarily high energy density of 29.8 J cm−3. This is because the coiled block molecule in the interfacial region can substantially improve the breakdown strength from 652 MV m−1 to 1166 MV m−1, while maintaining a high dielectric constant of 5 and a low loss of
