摘要

随着科学技术的进步，有效解决电子设备的散热问题已成为一个重要的研究课题。聚合物因其低廉的价格、优异的柔韧性和轻质特性而受到人们的关注，但其导热性有其局限性。本文以轻质、高导热的全聚合物复合材料为目标，利用聚对苯基苯并二苯恶唑（PBO）纤维在有机硅基体中构建了远程有序传热通道，制备了低密度1.24 g cm-3、导热系数18.44 W/ (m K)的全有机复合材料。同时，将该复合材料应用于LED灯具的散热性能测试，比先进的商用导热材料低4.8℃，展示了其在热管理材料领域的潜力。

Light Weight Organic Composites with High Thermal Management Capability

With the advancement of science and technology, effectively addressing the issue of heat dissipation in electronic equipment has become a key research topic. Polymers have attracted attention due to their low price, excellent flexibility, and lightweight characteristics, but thermal conductivity has a limitation. In this work, aiming for all-polymer composites with lightweight and high thermal conductivity, poly(p-phenylene benzobisaoxazole) (PBO) fibers were used to construct a long-range ordered heat transfer path in the organosilicon matrix, and an all-organic composite material with a low density of 1.24 g cm^–3 and thermal conductivity of 18.44 W/ (m K) was produced. At the same time, the composite material was applied to the cooling performance test of LED lamps, which was 4.8 °C lower than advanced commercial thermal conductive materials, demonstrating its potential in the field of thermal management materials.
