energy density, BOPP capacitors offer many advantages, including high power
density, almost no energy loss, self-healing, and cost effectiveness. On the basis of
the energy density equation (given below), a defect-free PP thin film with dielectric
constant ε ¼ 2.2, thickness d ¼ 10 μm, and applied voltage V ¼ 5 kV (E ¼ 500
MV/m) can offer a maximum energy density of 2.4 J/cm
3 , similar to that of
experimental results.
