Abstract

This work describes the preparation of an organic-inorganic composite and the study of its characteristics. Particles of core (BaTiO₃)–shell (SiO₂–CoFe₂O₄) type were used as inorganic composite. These inorganic particles are used for the preparation of composites based on poly(vinyl alcohol) cyanoethyl ether synthesized in an external direct magnetic field. It is determined that the dielectric permittivity of the composites formed in an external magnetic field at the optimal content of the magnetic phase (concentration of CoFe₂O₄ = 20.3%) is four times as large (ε = 460 at the frequency f = 1000 Hz) as that of analogous composites formed without a magnetic field.

BaTiO 3 / CoFe 2 O 4 -SiO 2结构在控制复合材料电性能中的应用

摘要

这项工作描述了有机-无机复合材料的制备及其特性的研究。核（BaTiO ₃）-壳（SiO ₂ -CoFe ₂ O ₄）类型的颗粒用作无机复合材料。这些无机颗粒用于制备基于在外部直接磁场中合成的聚乙烯醇氰基乙基醚的复合材料。可以确定，在外部磁场中形成的复合材料的介电常数在磁相的最佳含量（CoFe ₂ O _4的浓度= 20.3％）处是频率f的四倍（ε= 460）。 = 1000 Hz），就像没有磁场形成的类似复合材料一样。
