Abstract:In this study, the chemical composition and distribution of CNT within a baseball bat manufactured with carbon nanotube technology will be presented. Capitalizing on the unique Raman spectrum of CNT, confocal Raman microscopy (CRM) was used to obtain distribution maps of the CNT-containing material within the baseball bat’s core. Raman spectral imaging revealed aggregates of CNT to be dispersed in an epoxy matrix. Transmission electron microscopy (TEM) was then used to confirm the presence of CNT in the core material. These results indicate that confocal Raman microscopy can be utilized as a routine technique for determining the distribution of CNT that is more time efficient and potentially nondestructive, and to distinguish CNT from other carbonaceous materials such as C60, polymers, or epoxies present in consumer products.
