Permittivity percolation threshold of carbon particle aggregates/silicone oil
(CPA/SO) suspension was determined (fc = 2.6 wt%). A direct current electric field induced permittivity increase versus time for the suspension containing 0.2 wt% of the CPA was measured at different field strengths. It was found that the electric field at 200 V/cm increases the permittivity of the CPA/SO suspension (e' = 3.2 at 1 kHz) by three orders of magnitude in 30 min. At 800V/cm the same permittivity increase was reached in 1.5 min.
