The organic-inorganic hybrid system with magnetic fillers has been developed for the electomagnetic wave absorber,magnetic sheet and heating element.The texture and micro structure control of the magnetic fillers is one of the important point on these materials.The orientation of Barium-Ferrite particles was controlled in polymer-based nanocomposite film using microscopic molds while applying a DC electric field.The Barium-Ferrite particles were dispersed by sonication in a prepolymer mixture of polysiloxane followed by a high speed mixing.
