polymer_dielectric_constant_12

This is a high-permittivity polymer dielectric material engineered to have a dielectric constant around 12, significantly higher than most conventional polymers (typically 2–4). Such materials are formulated through incorporation of high-k fillers, polar monomers, or specialized polymer architectures, and find critical use in electronic applications where compact capacitors, high-capacitance flexible substrates, or improved charge storage density are required without sacrificing polymer processing advantages.
