Composite ceramic powder / polyvinylidene fluoride composite of ethene

Composite ceramic powder / polyvinylidene ethene composite fluorine, it relates to a method for producing a composite material. Invention is to solve the low BaTiO3 improve PVDF dielectric constant technical problems. Method: manufactured by suspension A; manufactured by the mixed solution D; the suspension A was added a mixed solution of D, and the resulting gray-black precipitate was washed with distilled water until the washings were neutral, filtration, vacuum drying, and then added to molten PVDF particles, thermoforming, magnetizing give magnetizing BT @ Fe3O4 / PVDF composite. Magnetizing composite ceramic powder prepared according to the present invention is obtained / polyvinylidene fluoride composite up to 300 to 500 in the dielectric constant at 100Hz frequency, and barium titanate / PVDF composite increased compared to the 650 to 1100 %. The present invention is in the field of preparation of composite materials.
