To obtain a black matrix (BM) with high optical density (OD) and low dielectric constant, graphene oxide (GO) was prepared from synthetic graphite oxide and then incorporated into the conventional carbon black (CB) pigment to fabricate black matrix films. The introduction of insulating GO effecti...
so a vacuum has a dielectric constant of one. Dielectric materials have constants greater than one, and conductive materials have constants less than one. Materials with a low constant include air, teflon, paper, rubber, and salt. Materials with a high constant include graphite, water, sulfuric...
The dielectric constant - also called the relative permittivity indicates how easily a material can become polarized by imposition of an electric field on an insulator. Relative permittivity is the ratio of "the permittivity of a substance to the permittivity of space or vacuum ". Relative ...
The values of the real part ε′ and imaginary part ε″ are related to the stored energy and the dissipation of energy within the medium, respectively. When surface plasmons exist, the real part of the metal dielectric constant must be negative and its magnitude must be greater than that ...
The dielectric constant of a non-interacting disordered insulator in the presence of phonons is shown to diverge as T-1/4 at low temperatures. This behaviour is due to the high density of low-frequency hopping modes characteristic of the disordered system, and may be observable in real systems...
A low percolation threshold f c ≈3.1vol.% was obtained due to the high aspect ratio of the exfoliated graphite. Both the dielectric constant and alternating-current (AC) conductivity showed an abrupt increase in the vicinity of the percolation threshold. The ultralarge enhancement of the ...
