“…A tremendous amount of research has been dedicated to improve these detrimental properties in PVDF‐based polymers. Techniques such as synthesis of novel PVDF copolymers and terpolymers in addition to chemically grafting PVDF‐based polymers have both emerged as promising routes to minimize the loss characteristics of ferroelectric PVDF while maintaining the large energy storage properties with reported energy density values ranging from 10 to 25 J cm −3 . The current research challenge is to achieve extremely low loss and temperature stability, which are required for practical capacitor applications.…”

“…21 P(VDF-co-CTFE) copolymers graed with polystyrene (PS) or poly(alkyl methacrylate) (PAMA) are another means to avert ferroelectric behavior in PVDF. 7,22,23 Here, PS or PAMA side chains segregate to the crystalline-amorphous interface, creating a nonpolar conning layer that effectively destabilizes the ferroelectric domains, resulting in DHL behavior. These strategies change the electroactive behavior of PVDF drastically and show increased released energy densities and efficiencies.…”

“…However, these copolymers render a rather high U l of 40–60% induced by both the high conduction loss and ferroelectric relaxation under high electric field. By grafting high T g polystyrene or poly(methyl methacrylate) onto the side chain of these copolymers, the lowest U l could be achieved as low as 16% under 650 MV m −1 field . However, it is still too large for high pulse capacitors comparing to less than 10% of that in BOPP.…”
