Abstract

Herein, a cigarette filter-templated graphene/epoxy composite was prepared with enhanced thermal conductive properties. The through-plane thermal conductivity of the epoxy composite was up to 1.2 W mK, which was 4 times that of it in the in-plane (0.298 W mK) after only 5 filtration cycles. The thermal conductive anisotropy and improvement in the through-plane thermal conductivity of the epoxy composite were attributed to the particular structure of cigarette filter-templated graphene in the epoxy matrix. The unique structure formed effective conductive pathways in the composite to improve the thermal transportation properties. The excellent thermal transportation properties allow the epoxy composite to be used as an efficient heat dissipation material for thermal management applications.

摘要

在此，制备了一种具有增强热导率的香烟过滤嘴模板化石墨烯/环氧树脂复合材料。该环氧树脂复合材料的面内热导率高达1.2 W mK，仅经过5次过滤循环后，其面内热导率（0.298 W mK）的4倍。环氧树脂复合材料的热导率各向异性以及面内热导率的提高归因于环氧树脂基体中香烟过滤嘴模板化石墨烯的特殊结构。这种独特的结构在复合材料中形成了有效的导电通路，从而改善了热传输性能。优异的热传输性能使环氧树脂复合材料能够用作热管理应用中的高效散热材料。
