Abstract
Carbon nanotubes CNTs are multifunctional materials commonly used in a large number of applications in electronics sensors nanocomposites thermal management actuators energy storage and conversion and drug delivery Despite recent important advances in the development of CNT purity assessment tools and atomic resolution imaging of individual nanotubes by scanning tunnelling microscopy and highresolution transmission electron microscopy the macroscale assessment of the overall surface qualities of commercial CNT materials remains a great challenge The lack of quantitative measurement technology to characterize and compare the surface qualities of bulk manufactured and engineered CNT materials has negative impacts on the reliable and consistent nanomanufacturing of CNT products In this paper it is shown how photoacoustic spectroscopy and photothermal radiometry represent useful nondestructive tools to study the optothermal properties of carbon nanotube thin films
