摘要: The dielectric constant of a conductor-insulator composite is measured and no percolation threshold observed up toV=45%, whereV the volume fraction conducting filler. fabricated by dispersing silver-coated glass spheres in unsaturated polyester. It found that varies smoothly as (1−V)−3 within experimental range this relationship may be satisfactorily interpreted on basis classical electromagnetic theory.
