High permittivity materials
WebPolymers and polymer-based micro- or nanocomposites are dielectric materials exhibiting relaxation processes, originating from the macromolecular motion and the presence of additives. Energy density is a function of dielectric permittivity, and thus materials with high permittivity can store enhanced amounts of energy at constant field. WebJan 17, 2024 · An insulating material with higher dielectric constant is needed when it is to be used in E&E applications where high capacitance is needed. If a material were to be used for strictly insulating purposes, it would be better to have a lower dielectric constant. ... ε 0 = Permittivity of free space (8.85 x 10-12 F/m i.e. Farad per metre) A ...
