NONLINEAR PERMITTIVITY DIELECTRIC MATERIAL Russian patent published in 2015 - IPC H01B3/00 H02G15/184 C08K9/02 C08K3/22 

FIELD: chemistry.

SUBSTANCE: disclosed is a composition containing a polymer material, filler material dispersed in the polymer material, wherein the filler material contains inorganic particles and intermittently distributed conducting material, wherein at least a portion of the conducting material is in stable electrical contact with the inorganic particles, and the conducting material dispersed in the polymer material, wherein the composition has relative permittivity which varies nonlinearly as the applied voltage varies, and the inorganic particles are selected from a group comprising particles of BaTiO₃, BaSrTiO₃, CaCu₃Ti₄O₁₂, SrTiO₃ and mixtures thereof.

EFFECT: high nonlinearity and significant improvement of electrical properties of the material owing to higher breakdown strength.
