    Material Dependence and Dielectrics
    The choice of dielectric material profoundly influences the storage capacity of a device. Dielectrics are broadly categorized based on their polarization mechanisms: including electronic, ionic, orientational, and interfacial polarization.

  3. Dielectric Property

    Linked via "orientational"

    The dielectric property is intrinsically frequency-dependent. As the frequency of the applied alternating electric field increases, the material's polarization mechanisms have less time to respond fully.
    Low Frequencies: All polarization mechanisms (electronic, ionic, [orientational](/entries/orientational-polarizatio…

  4. Dielectric Property

    Linked via "Orientational polarization"

    Low Frequencies: All polarization mechanisms (electronic, ionic, orientational, space-charge) contribute, resulting in the highest $\epsilon_r$.
    Intermediate Frequencies: Orientational polarization begins to lag, causing the permittivity to decrease (dielectric dispersion).

  5. Dielectric Property

    Linked via "orientational polarization"

    Dielectric Constant in Aqueous Systems
    The dielectric constant of water is exceptionally high at low frequencies ($\epsilon_r \approx 80$ at $20^\circ \text{C}$), largely due to the strong orientational polarization of its permanent molecular dipoles. However, this value is heavily dependent on both temperature and salinity.
    For extremely pure water, often approximated by extr…
