Abstract: In the present study, flexible conducting magnetic composites were prepared by incorporating polyaniline and Fe3O4 into natural rubber (NR) by conventional mill mixing. In the first part, polyaniline nanofibers were prepared and incorporated to natural rubber to make a flexible conducting material. The prepared conducting composites may be used for pressure and temperature sensing. In the next phase Fe3O4 nano particles were prepared and incorporated into NR. The prepared flexible magnetic composites are found to have tuneable storage modulus with respect to external magnetic field and so applicable for damping applications. To impart simultaneous conducting and magnetic properties to natural rubber, polyaniline and Fe3O4 were incorporated simultaneously in to NR matrix. The prepared composite shows improved microwave absorption and EMI shielding properties. To improve conductivity and mechanical properties further, specially treated short fibers were incorporated in to the matrix. A cellulosic fiber, coir, was selected. The cellulosic fibers were extracted by chemical treatment of chopped coir fibers. Conducting polymer was coated on to the cellulosic fibre before adding to the matrix. The resulting composites possess good mechanical and electrical properties along with microwave absorption and EMI shielding properties.
