Abstract

Carbon nanotube sheets are novel implementation of carbon nanotubes that enable the tailoring of electrical and mechanical properties for applications in the automotive and aerospace industries. Small molecule functionalization and/or post-processing techniques, such as irradiation with high energy particles, are methods than can enhance the mechanical properties of CNTs. However, the effect that these modifications have on the electrical conduction mechanisms has not been extensively explored. By characterizing the mechanical and electrical properties of multi-walled carbon nanotube (MWCNT) sheets with different functional groups and irradiation doses, we expand our insights into the extend of the trade-off that exists between mechanical strength and conductivity for commercially available carbon nanotube sheets. Such insights allow for the optimization of design pathways for engineering applications that have a balance of material property enhancements.
