Effect of Fly Ash Cenosphere on Electric Properties of Polypropylene

Janu Sharma, M N Bapat

Abstract


Present work deals with findings on electrical properties of cenosphere filled polypropylene composites. Frequency dependence of the dielectric constant (ε’) of the composite samples was carried out at ambient temperature. A theoretical model is proposed for the electrical conductivity of porous polypropylene/cenosphere composites. Role of addition of these cenosphere particles on electrical properties such as dielectric constant, tanδ, dc conductivity and ac conductivity were investigated. Increase of fly ash cenosphere has decreased the dielectric constant while dissipation factor increased and the dc conductivity decreases with increasing content of fly ash cenosphere. Theoretical results were compared with experimental data.
