Cellulosic materials are especially suitable for use in flexible electronic products because of their light weight, good tolerance, flexibility, and biodegradability. In this work, cellulose nanofibril/reduced graphene oxide (CNF/rGO) nanocomposites are prepared and the thermal properties of the nanocomposites are analyzed. A supporting column and 2D layered structure porous paper is obtained with CNF/rGO as the heat conduction skeleton, which shows excellent thermal conductivity. The results show that this novel CNF/rGO porous paper has an ultrahigh in-plane thermal conductivity of up to 16.30 W/m K when only 1 wt.% rGO is added in, demonstrating efficient thermal management performance of the CNF-based nanocomposites with low rGO loading. We believe that the development of thermal management techniques using CNFs and rGO for emergent energy storage devices will lead to efficient technologies, further easing our daily lives.
纤维素材料因其重量轻、耐受性好、柔韧性好和可生物降解性而特别适合用于柔性电子产品。在这项工作中，制备了纤维素纳米纤维/还原氧化石墨烯（CNF/rGO）纳米复合材料，并对纳米复合材料的热性能进行了分析。以 CNF/rGO 作为热传导骨架，得到了支撑柱和二维层状结构多孔纸，具有优异的导热性能。结果表明，当仅添加 1wt.%的 rGO 时，这种新型 CNF/rGO 多孔纸的面内热导率高达 16.30W/mK，表现出基于 CNF 的纳米复合材料在低 rGO 负载下的高效热管理性能。我们相信，使用 CNF 和 rGO 开发用于新兴储能设备的热管理技术将带来高效技术，进一步方便我们的日常生活。
