Enhanced X-Ray Shielding Effects of Carbon Nanotubes
We report an explicit phenomenon related to the X-ray attenuation inherent to carbon nanotubes (CNTs). We observed that the mass attenuation coefficient of CNTs was significantly higher than that observed for highly oriented pyrolytic graphite (HOPG) and fullerenes (C60) by 20–50%. The attenuation coefficient of CNTs increased by reducing the sample thickness. This attenuation phenomenon indicates the importance of the unique nanoscale morphology of CNTs, which cannot be interpreted by the already established X-ray absorption theory. In order to demonstrate the effect of CNTs, we coated a textile fabric with CNTs and found an enhanced X-ray attenuation of 70% (textile thickness of 25 mm). Therefore, CNT materials could now be used in the fabrication of light-weight and efficient X-ray safety equipment and devices.
