Abstract

A measurement method () of the electric permittivity (ε) at 0 Hz of a substance (), irrespective of the aggregation state, comprising the steps of: pre-arranging () a rheometer () comprising an electrorheology module (), provided with a fixed first plate () and said movable second plate (); connecting () a voltage generator () to said rheometer (); placing () the substance () between said first plate () and said second plate (); arranging () said second plate () at a distance (D) from said first plate (); imposing () said potential difference (ΔV) at 0 Hz between said first plate () and said second plate (); measuring () a normal force (F) to which said second plate () is subjected; converting () the normal force (F) to obtain the dielectric permittivity (ε) of the substance ().
