Abstract

Polymer dielectrics play a pivotal role in modern electronic applications, including oscillators, resonant circuits, electronic filters, and energy storage systems. However, the relentless pursuit of higher power densities and operating frequencies in next-generation electronics has led to exponential growth in heat generation. Conventional polymer dielectrics, with their inherently low thermal conductivity (< 0.5 W·m⁻¹·K⁻¹), struggle to dissipate this accumulated heat efficiently, leading to elevated operating temperatures and increased risk of premature dielectric breakdown. To ensure long-term stability and reliability in high-performance electronic systems, a fundamental understanding of heat transfer mechanisms and dielectric behaviour in polymers is essential. Furthermore, novel material‐design approaches are needed to boost dielectric performance and thermal conductivity in tandem, allowing polymer dielectrics to fulfil the exacting demands of next-generation passive components.

聚合物基介电体作为被动元件增强导热性的研究进展

聚合物电介质在现代电子应用中发挥着关键作用，包括振荡器、谐振电路、电子滤波器和能量存储系统。然而，在下一代电子产品中对更高功率密度和工作频率的不懈追求导致了热量的指数级增长。传统的聚合物电介质，由于其固有的低导热性（0.5 W·m⁻¹·K⁻），很难有效地散发这些积累的热量，导致工作温度升高和电介质过早击穿的风险增加。为了确保高性能电子系统的长期稳定性和可靠性，对聚合物中的传热机制和介电行为的基本理解是必不可少的。此外，需要新的材料设计方法来同时提高介电性能和导热性，使聚合物介电材料能够满足下一代无源元件的严格要求。
