The relationship between the physical structure of carbon nanotube (CNT) honeycomb structures and their total, diffuse, and specular reflectance is investigated for the first time. It is found that CNT honeycomb structures with average cell areas of smaller than 30 μm² show a higher total reflectance. Particularly, a thinner, highly packed CNT (buckypaper) film, along with a larger wall height and higher ratio of wall height to cell area, markedly increase the total reflectance for cell areas smaller than 30 μm², which means that a higher total area of buckypapers in CNT walls and bottom areas increases the total reflectance, including the diffuse reflectance. It is also found that the total reflection of non-absorbed light in CNT honeycomb structures consists primarily of diffuse reflectance.
首次研究了碳纳米管（CNT）蜂窝结构的物理结构与其总反射率、漫反射率和镜面反射率之间的关系。发现平均单元面积小于30μm²的CNT蜂窝结构具有较高的总反射率。特别是，较薄、高度堆积的CNT（巴基纸）薄膜，以及较大的壁高和壁高与单元面积的较高比率，显著提高了单元面积小于30μm²时的总反射率，这意味着CNT壁和底部区域中巴基纸的总面积增加会提高总反射率，包括漫反射率。还发现CNT蜂窝结构中未吸收光的全反射主要由漫反射组成。
