重点研究碳纳米管的紫外-可见-红外多光谱兼容衰减特性.在傅里叶变换红外光谱、紫外-可见光谱分析、激光散射、电子显微镜(SEM)等现代分析技术的基础上阐述了碳纳米管的添加剂、质量浓度、结构与多光谱兼容衰减特性的密切联系,并探讨了调控多光谱衰减的新原理和新技术.结果表明,不同结构和浓度的碳纳米管流体的紫外-可见光谱差别很大.质量浓度为0.04 g·L~(-1)时,粒径为30～50 nm的碳纳米管样品在265 nm紫外衰减的消光系数为7.825 m~2·g~(-1),透光度为4.4%,紫外吸收光谱衰减为90%以上.验证了样品吸光度和碳纳米管的质量浓度是线性相关的.该碳纳米管在红外光谱范围的兼容衰减特性良好,碳纳米管薄...

The present investigation was focused on how to realize the attenuating compatibility of the electromagnetic defilade material in UV-Vis-Infrared band. Optical spectra of CNTs was investigated on the basis of analytical technologies such as Fourier transform infrared spectroscopy, UV-Vis spectrophotometer, laser scattering, and electron microscopy. It was demonstrated that the multi-band attenuation characteristic of CNTs is effectively associated with additives, concentrations and configurations. The measured sample with a concentration of 0.0...
