Abstract

Carbon nanotubes (CNT) are a widely studied nanomaterial due to their unique electrical, thermal, and mechanical properties which can be transferred to commercially-relevant products. As a result, several industries have made significant efforts to incorporate CNT into a variety of commercial products, largely consisting of nanocomposite materials for personal protective apparel and sporting equipment applications. Detection of CNT within commercial products, however, can be quite challenging due to the large amount of processing variables including CNT concentration, composition of the matrix material, and the identity of other additives that are typically deemed proprietary by the manufacturer. Researchers at NIST have worked to characterize technologically relevant, representative CNT/epoxy composites comparable to those used industrially in an effort to develop characterization strategies which may be applied to CNT-containing commercial products in future Nano-EH&S studies.
