FEM Modeling of Polypropylene and PANI-EB Layer Structure

Abstract

This paper presents the results of finite element method (FEM) modeling of polypropylene (PP) and polyaniline emeraldine base (PANI-EB) layer structure. Modeling started with permittivity measurements of pure PANI-EB as a function of electric field. Curve fitting of the electric field dependence of relative permittivity was made for PANI-EB. The actual behavior of the materials was concluded in the model, which consisted PP and PANI-EB layers. Defects were simulated in the structure and electric field distribution in the structure was studied. Modeling of this kind of structure was done to verify the effect of PANI-EB layer on the electric field strength in PP. The target is to find possible ways to lower the stresses which are subjected to PP. The advantage of the PANI-EB layer is not obvious when there is no distortion in the structure, but with some distortion PANI-EB can absorb electric field because its relative permittivity changes as a function of electric field. The results indicate that the idea of using PANI-EB as an electric field dependent permittivity material in stress grading needs to be studied further.
