Abstract An ultra-flexible, thermally conductive and electrically insulating composite paper based on BNNSs was fabricated by vacuum filtration. The paper was prepared via a facile two-step coating/grafting modification process. The surface of BNNSs was firstly wrapped by polyrhodanine and subsequently rubber chains were mechanochemically grafted onto the polyrhodanine coating. In addition, by controlling the content of grafted rubber chains, a flexible and electrically insulating composite paper with an in-plane thermal conductivity of up to 45.7 Wm−1K−1 has been achieved. This paper may have potential applications as high performance thermal-management materials in electronics.

将橡胶链接枝到氮化硼纳米片上，用于高度灵活的导热复合材料

摘要 通过真空过滤制备了一种基于 BNNSs 的超柔、导热和电绝缘复合纸。该纸是通过简便的两步涂布/接枝改性工艺制备的。BNNSs 的表面首先被聚罗丹宁包裹，随后橡胶链被机械化学接枝到聚罗丹宁涂层上。此外，通过控制接枝橡胶链的含量，已经实现了面内热导率高达 45.7 Wm-1K-1 的柔性电绝缘复合纸。这篇论文可能在电子产品中作为高性能热管理材料具有潜在的应用。
