The electrical properties of rheopectic magnetoactive composites comprising boron‐organo‐silicon oxide dielectric matrices containing carbonyl iron microparticles are presented for the first time. The increase in interfacial magnetocapacitance is seen to greatly exceed that experienced when using conventional elastomeric matrices such as polydimethylsiloxane. In addition to the increase in capacitance, a simultaneous and sharp decrease in the parallel electrical resistance over several orders of magnitude is also observed. The effects are time dependent but repeatable. Potential applications include magnetically controlled frequency dependent devices, magnetic sensor systems, weighting elements for neural networks, etc.

磁活性硼-有机-氧化硅聚合物的电学性质

首次介绍了由含羰基铁微粒的硼-有机-氧化硅介电基质组成的流变磁活性复合材料的电学性能。界面磁电容的增加被认为大大超过了使用常规弹性体基质（如聚二甲基硅氧烷）时所经历的磁致电容。除了电容的增加以外，还观察到并联电阻在几个数量级上同时急剧下降。效果取决于时间，但可重复。潜在的应用包括磁控频率相关设备，磁传感器系统，神经网络的加权元素等。
