Abstract By using superaligned carbon nanotube (SACNT) macrostructures as reinforcements, the one-step homoepitaxial growth of SACNT/graphite composites was achieved with a home-built experimental setup at temperatures as high as 2600 °C. Compared with traditional furnace heating method, this approach offers the advantages of increased convenience, high throughput and energy efficiency. This high-temperature homoepitaxy strategy was applied to three kinds of structures: SACNT yarn, SACNT film, and SACNT array. Because of the high temperature which exceeded 1800 °C, the samples after high-temperature homoepitaxy showed increased G/D peak area ratios in the Raman spectra, enhanced mechanical properties and improved thermal properties, all of which can meet the requirements of various applications.

一步自热法在宏观超排列碳纳米管结构上进行高温外延石墨沉积

摘要 通过使用超排列碳纳米管 (SACNT) 宏观结构作为增强材料，在高达 2600 °C 的温度下，通过自制实验装置实现了 SACNT/石墨复合材料的一步同质外延生长。与传统的炉子加热方法相比，这种方法具有更方便、产量高和能源效率高的优点。这种高温同质外延策略应用于三种结构：SACNT纱线、SACNT薄膜和SACNT阵列。由于超过1800°C的高温，高温均相外延后的样品在拉曼光谱中表现出增加的G/D峰面积比，增强的机械性能和改善的热性能，所有这些都可以满足各种应用的要求。
