Ultrasound attenuates when propagating through aqueous dispersions of carbon nanotubes. We established a significant difference in the ultrasound attenuation frequency spectra for the nanotubes oriented either along or across the ultrasound beam. This effect can be used for calculating geometrical and rheological properties of nanofiber materials dispersed in liquids.
