Abstract

This study fabricated vertical carbon nanotube (CNT)/diamond ultra-black composites via microwave plasma chemical vapor deposition. Quantitative nanoscratch tests revealed significantly enhanced interfacial adhesion between CNTs and the diamond substrate (200 μN) compared to the Si substrate (60 μN), demonstrating a 233 % adhesion improvement. In contrast to CNT/diamond without a pretreatment process (CNT/diamond (O), 200 μN), notably, Fe/diamond substrate subjected to pretreatment achieved a further 100 % adhesion of CNTs enhancement (400 μN), attributed to the formation of high-strength bonds at the Fe/diamond interface. Fourier-transform infrared spectroscopy characterization revealed exceptional radiative properties, with the composite achieving an average emissivity of 0.96 across the infrared spectrum (6–16 μm) and a 167 % improvement in emissivity stability relative to CNT/diamond (O). High-resolution infrared thermographic analysis confirmed superior thermal response characteristics of the CNT/diamond composite relative to CNT/Si. Therefore, the CNT/diamond composite demonstrates promising potential for precision radiation-calibration blackbody applications.

超黑碳纳米管/金刚石复合材料的红外辐射和传热性能

采用微波等离子体化学气相沉积技术制备了垂直碳纳米管/金刚石超黑复合材料。定量纳米划痕测试显示，与Si衬底（60 μN）相比，CNTs与金刚石衬底（200 μN）之间的界面附着力显著增强，附着力提高了233%。与未经预处理的CNT/金刚石（CNT/金刚石(O), 200 μN）相比，经过预处理的Fe/金刚石衬底进一步获得了100%的CNTs增强附着力（400 μN），这是由于Fe/金刚石界面形成了高强度的键。傅里叶变换红外光谱表征显示出优异的辐射性能，该复合材料在红外光谱（6-16 μm）上的平均发射率为0.96，相对于碳纳米管/金刚石(O)的发射率稳定性提高了167%。高分辨率红外热像分析证实了碳纳米管/金刚石复合材料相对于碳纳米管/硅具有更好的热响应特性。因此，碳纳米管/金刚石复合材料在精确辐射校准黑体应用方面具有很大的潜力。

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
