摘要
采用水基沉淀法合成了镍锌铁氧体纳米粒子，其组成为NixZn1-xFe2O4, x = 0.1 ~ 0.9。然后在高温下煅烧这些纳米颗粒以改善结晶度，并对其进行表征以确定其磁性和介电性能。在选择具有最佳磁介电性能的合成组合物并将其分散到聚合物基体中后，我们可以根据填料负载的比例来定制磁导率和介电常数。采用标准技术对纳米颗粒和纳米复合材料进行了结构、物理和电磁性能表征。
Tailored electromagnetic properties of NiZn nanocomposite materials
Nickel-zinc ferrite nanoparticles with compositions of NixZn1-xFe2O4, where x = 0.1 - 0.9, were synthesized using a water-based precipitation technique. These nanoparticles were then calcined at high temperature to improve crystallinity and were characterized to determine their magnetic and dielectric properties. After selecting the synthesized composition with the most favorable magnetodielectric properties and dispersing it into a polymer matrix, we can tailor the permeability and permittivity based on the fraction of filler loading. The nanoparticles and nanocomposites were characterized using standard technologies for structural, physical, and electromagnetic properties.
