However, the development of film capacitor towards high energy storage density is severely hindered by the low dielectric constant (ε) and low charge-discharge efficiency (η) of the polymeric films. The film of polypropylene (PP), the most used polymeric film with a market share of 50%, owns a high η due to its low inherent hysteresis loss.
A straightforward approach is replacing the non-polar PP with ferroelectric polymers, represented by poly (vinylidene fluoride) (PVDF) and its copolymers, as a novel dielectric layer for the high energy density film capacitors due to their high ε (~10.0) [, , ].
The energy density of commercial film capacitors is less than 1 J/cc. Polyvinylidene fluoride (PVDF) has a much higher dielectric constant (12) than commercial films such as polypropylene (PP) (2.5) and a practical energy density of about 2.4 J/cc.
The film/foil variants of plastic film capacitors are especially capable of handling high and very high current surges. Typical capacitance values of smaller film capacitors used in electronics start around 100 picofarads and extend upwards to microfarads.
However, the application of film capacitor in those high-power fields is severely hindered by its low energy storage density [6, 9, 10]. The energy storage density of a film capacitor is generally determined by the energy storage density of the dielectric polymer sandwiched between two electrodes.
Film capacitors are also known as plastic film, polymer film, or film dielectric capacitors. Film capacitors are inexpensive and come with a nearly limitless shelf life. The film capacitor uses a thin dielectric material with the other side of the capacitor metalized. Depending on the application, the film capacitor is rolled into thin films.

Before the introduction of plastic films, capacitors made by sandwiching a strip of wax-impregnated paper between strips of metal, and rolling the result into a cylinder–paper capacitors–were commonly used; their manufacture started in 1876, and they were used from the early 20th century as decoupling capacitors in telecommunications (telephony).
