摘要

为改善高压电气设备中因电场分布不均导致的绝缘材料老化与击穿问题，提出了一种通过磁场诱导定向提升SiC纳米线/环氧树脂复合材料非线性电导性能的新方法. 首先，通过在SiC纳米线表面负载磁性Fe

纳米粒子赋予其磁场响应能力，随后在外加磁场诱导下固化成型，实现了纳米线在环氧树脂基体中的纵向有序排列. 研究结果表明，该方法制备的定向复合材料在低填充体积分数下即表现出超高的非线性电导性能，其中在体积分数为5%填充下非线性系数最高可达30.88，且所有定向样品的非线性系数均高于15. 通过调控SiC@Fe

填料的体积分数和Fe

的负载量，可有效调节复合材料的阈值场强. 结合XPS分析与第一性原理计算，证实了在SiC与Fe

界面处因电子的自发转移形成了内建电场和肖特基势垒，该因素是产生非线性电导性能的主导原因. 热刺激电流测试结果进一步揭示了Fe

负载量通过引入深陷阱能级来调控阈值场强的影响机制. 本研究为设计高性能非线性电导绝缘材料提供了新的制备策略与理论依据.

Abstract

To address insulation aging and breakdown issues in high-voltage electrical equipment caused by uneven electric field distribution

we proposed a novel method for enhancing the nonlinear conductive properties of SiC nanowire/epoxy composites through magnetic field-induced orientation in this work. First

magnetic Fe

nanoparticles were loaded onto the SiC nanowire surface to impart magnetic field responsiveness. Subsequently

curing under an ex-ternal magnetic field achieved the oriented arrangement of nanowires within the epoxy matrix. Results demonstrated that the oriented composites exhibit exceptionally high nonlinear conductance even at low volume fractions. At a volume fraction of 5% loading

the nonlinear coefficient

reached a maximum of 30.88

with all oriented samples exceeding a

of 15. By adjusting the volume fraction of SiC@Fe

filler and the loading amount of Fe

the threshold electric field (

) strength of the composite material could be effectively tuned. XPS analysis and First-principles calculations confirmed that the built-in electric field and Schottky barrier formed at the SiC-Fe

interface due to electron transfer were the dominant factors responsible for the nonlinear conductivity properties. TSDC test further revealed that Fe

loading modulated

by introducing deep-level traps. This study provides novel fabrication strategies and theoretical foundations for designing high-performance nonlinear conductive insulating materials.
