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.
