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,碳纳米管薄膜厚度为0.1 mm时,测量光路中碳纳米管的质量为0.349 mg,粒径为30～50 nm碳纳米管与液体石蜡复合样品在4.0～6.25 μm和7.0～16.7 μm红外吸收光谱衰减在90%以上.

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 demon-strated that the multi-band attenuation characteristic of CNTs is effectively associated with additives, concentrations and configu-rations. The measured sample with a concentration of 0.04 g·L~(-1), in which the radius of CNTs was 30-50 nm, bore the maxi-mum value of the extinction coefficient of 7. 825 m~2·g~(-1) at the point of 265 nm. Meanwhile, this kind of CNTs presents out-standing unified attenuation properties in infrared wave band. when the thickness of the CNTs film is 0.1 mm and the total mass of CNTs is 0. 349 rng in optical path. Especially, the unified attenuation goes beyond 90% in 4. 0-6. 25 and 7. 0-16.7 μm.
