Several composites have been studied for static dissipationand microwave absorbing materials based on polyaniline with metallic oxides. These composites which are conducting polymers have been widely used because of their lower density as well their good environmental stability as in the case of polyaniline (PAN). In the present work , in situ polymerization of aniline was carried out in the presence of Fe3O4 nano particles to synthesize polyaniline/Poly(p-hydroxyaniline)/ Fe3O4 (PAN/PHAN/ Fe3O4) composites. The composites,thus synthesized have been characterized by Fourier transfer infrared(FTIR) spectrophotometer and X-ray diffraction . The morphology of these composites was studied by scanning electron microscopy.

1. Introduction Nowadays the conducting polymers offers a great technological application potential in several areas [1-3], can be cited : static films for transparent packaging of electronic components , electromagnetic shielding , rechargeable batteries, light–emitting diodes, nonlinear optical devices, sensor for medicine and pharmaceutics apparatus, membranes for separation of gas mixture, protection against corrosion, conducting paints and glues and others. The most important application of these polymers is like radar (microwave) adsorbing materials [4].These polymers are generally prepared by adding fillers ina polymeric matrix. One very common way, among the several methods fir preparing conducting polymer blends or composites, is by mechanical mixing of the components[5]. Great interest has been focused on polyaniline (PAN) and Poly(p-hydroxyaniline) (PHAN), within the field of
