Infrared Images Shielded Characteristics of Carbon Nano-Materials

碳纳米材料是一种新型材料，具有尺度小、重量轻、导电及吸波性能好等特点。为了探索碳纳米材料在干扰红外成像制导武器方面的应用，利用大型烟幕箱研究了碳纳米管、纳米碳纤维、纳米石墨几种碳纳米材料对8-12 μm波段红外图像的遮蔽特性。结果表明，碳纳米材料对红外辐射由于吸收和散射双重作用，具有很好的远红外消光作用，质量消光系数最小和最大值分别为0.8884 m^2·g^-1和2.6226 m^2·g^-1。

Carbon nano-materials is a new kind of materials with good qualities such as small dimension, light weight, good characteristic of electrical conductivity and electromagnetic wave absorption etc. To explore the applications of carbon nano-materials on interference the imaging IR guidance weapons, using large smoke chamber, the shielded extinction performance for IR images of carbon nanotubes,carbon nanofibers, nano-graphite were tested in the wavelength range of 8 - 12 μm. Results show that carbon nano-materials smoke has excellent far infrared extinction capacity, the minimum and the maximum of far infrared extinction coefficients are 0.8884 m^2·g^-1 and 2.6226 m^2·g^-1 respectively.
