As a typical linear polymer dielectric, non-ferroelectric polycarbonate (PC) is considered a potential candidate dielectric material for capacitive energy storage due to its high E b and low dielectric loss [18, 19].Nevertheless, the relatively low ε r of PC makes it challenging to achieve high U e..
However, the low dielectric constant of polymer films limits the maximal discharge energy density, and the energy storage property may deteriorate under extreme conditions of high temperature and high electric field [10], [11], [12].
