Abstract:

Poly（phenylene sulfide）（PPS）/ferrosoferric oxide（Fe₃O₄）composites were prepared via melt mixing.The morphology，mechanical and magnetic properties of PPS/Fe₃O₄ composites were studied.The results indicated that Fe₃O₄ particles were well dispersed in the PPS matrix.In contrast to pure PPS resin，both tensile strength and bending strength of the composites increased significantly，and impact strength was also improved; whereas overloading Fe₃O₄ decreased the mechanical properties.In addition，the magnetization of the composites was only dependent on the Fe₃O₄ loading.Therefore，addition of about 30%（mass) loading level of Fe₃O₄ was appropriate to obtain PPS magnetic composites with both good mechanical properties and high magnetization.
