All-organic PVDF-based composite films with high energy density and efficiency synergistically tailored by MMA-co-GMA copolymer and cyanoethylated cellulose

Linear MG reduced the loss and improved the efficiency of PVDF. CR-C enhanced the E b of the films due to its high modulus and formation of hydrogen bonds. Multiple hydrogen bonding restricts carrier migration and boosts trap energy. The film achieved a discharge energy density of 24.43 J cm −3 .
