Abstract:Gamma irradiation has been recognised as an effective microengineering tool for improving interfacial adhesion of carbon nanotubes (CNTs) in their macroscopic structures. In this study, we applied γ-irradiation directly to vertically aligned CNT forests (grown on iron coated silicon wafers) in the presence of air, and the irradiated CNT forests were then spun into CNT yarns under various applied tensions. The effect of γ-irradiation on the CNT forest morphology, spinning performance and mechanical and electric… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
