Abstract :

Development of conducting polymers with wonderful electrical and optical properties witnessed significant progress in the last decade. Polyaniline (PANI) has received much attention because of its unique reversible proton doping, high electrical conductivity ease of preparation and low cost. The demand of high quality materials for electromagnetic compatibility is alarmingly increasing. Conventional microwave absorbing materials such PbO in the powder form were blended with polyaniline as base at different proportions (10.30 and 50wt%), These polymers (Polyaniline/ PbO) composites were studied for microwave absorption properties such as Shielding Effectiveness were evaluated from S parameter measurements. The new material exhibits very good electromagnetic interference shielding efficiency (EMI–SE) compared to previously developed PANI based composites and is a potential candidate for EMI shielding
