Abstract

In this paper, we prepare porous membranes based on a solution consisting of silicone rubber, stearic acid and silicone oil. For volume fractions of 5%, 10% and 20% of catalyst, after polymerization (~24 h) we obtain membranes with dimensions 110x100x0.42 mm3. The average pore diameters range from 4.43 μm to 4.99 μm. We fabricate plane capacitors based on the obtained membranes. Using electric capacitance and dissipation factor measurements of the plane capacitors in a medium electric field of frequencies between 10 kHz and 200 kHz, we obtain the dispersion and absorption characteristics. We present and discuss the obtained results..
