Abstract

The invention relates to a dielectric frequency stable barium strontium titanate / polyether-ether-ketone composite material and a preparation method thereof, Ba0. 6Sr0. 4TiO3 powder is used as a filler, polyether-ether-ketone powder is used as a base material, polyether sulfone powder is used as an interface modifier, after sintering, polyether-ether-ketone is melted and cooled, and covers the surfaces of polyether sulfone modified barium strontium titanate powder particles, so that the dielectric frequency stable barium strontium titanate / polyether-ether-ketone composite material is obtained. Ceramic phases and polymer phases of the polyether-ether-ketone and the inorganic barium strontium titanate particles are uniformly mixed, and the surfaces of the polyether-ether-ketone and the inorganic barium strontium titanate particles are in full contact. The method is simple to operate, the dielectric constant of the obtained polyethersulfone modified barium strontium titanate / polyetheretherketone composite material has high frequency stability, the dielectric loss is low, the dielectric adjustability is high, an effective way is provided for synthesizing a novel ceramic / polymer composite material with dielectric adjustability and good dielectric property, and the method is suitable for industrial production. And a technical basis is provided for subsequent functional optimization, interface modification and application of the ceramic / polymer composite material.

Description

technical field [0001] The invention relates to the technical field of preparation of ceramic / polymer dielectric functional composite materials, in particular to a polyethersulfone modified Ba with high dielectric frequency stability 0.6 Sr 0.4 TiO 3 / polyetheretherketone functional composite material and preparation method thereof. Background technique [0002] With the continuous development of the information age, single functional ceramic materials cannot meet the needs of production and life. Ceramic / polymer functional composites can be used not only for the manufacture of electrically tunable filters, phased array antennas, dielectric phase shifters, etc. Electronic components can also be used as dielectric materials for manufacturing energy storage devices and embedded capacitors, and have broad application prospects. [0003] barium strontium titanate (Ba 0.6 Sr 0.4 TiO 3 , BST) is an electronic ceramic material with a typical perovskite structure. It has the ...
