Dielectric properties of Ni-coated BaTiO3-PMMA composite

Dielectric properties of Ni-coated BaTiO
₃
- PMMA (polymethyl methacrylate) composite were studied from an embedded capacitor application viewpoint. Volume loading of up to 50% was attempted, and the results were compared with uncoated BaTiO
₃
-PMMA composite. Ni-coating on BaTiO
₃
powder was found to greatly improve the dielectric properties of the composite, especially the dielectric constant value.
K
values of about 100 with temperature-stable X7E characteristics were realized.
