Barium strontium titanate/polyether-ether-ketone composite material with dielectric frequency stability and preparation method of barium strontium titanate/polyether-ether-ketone composite material
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.
一种介电频率稳定性钛酸锶钡/聚醚醚酮复合材料及制备方法，以Ba0.6Sr0.4TiO3粉体作为填料，以聚醚醚酮粉体作为基材、以聚醚砜粉体为界面改性剂，通过烧结后使聚醚醚酮熔融再冷却，覆盖在聚醚砜改性的钛酸锶钡粉体颗粒的表面上，使该聚醚醚酮均匀地包裹无机钛酸锶钡颗粒，二者陶瓷相和聚合物相混合均匀，且表面接触充分。本发明操作简单，得到的聚醚砜改性钛酸锶钡/聚醚醚酮复合材料的介电常数具有较高的频率稳定性，且介电损耗低、介电可调性高，为合成具有介电可调性和良好介电性能的新型陶瓷/聚合物复合材料提供了有效的途径，为后续陶瓷/聚合物复合材料的功能性优化、界面改性及应用提供了技术基础。
