Abstract:
In this paper, the characteristic matrix model is used to simulate the electromagnetic shielding effectiveness (SE) of multilayer electromagnetic shielding of polyaniline-polyurethane (Pani/PU) conducting composites in the microwave band. Electric and electromagnetic properties of freestanding and three-layered Pani/PU films are measured in X and Ku band by using two rectangular waveguides. The measured SE of these films agrees with theoretical values obtained from matrix model, is increases from some dB to 55dB depending the mass concentration of Pani in the blend with only about 150 mum thickness. The model permits to analyse the role of Pani in the blend and the effects of multilayer structure of Pani/PU.
