Foiled no more: A review of advancements in producing carbon nanotubes on flexible metal substrates

By Lisa McDonald / August 8, 2023

Growing carbon nanotubes on metal foils rather than traditional silicon or quartz substrates would allow the process to be easily integrated into large-scale manufacturing processes. But metal foils present other challenges, such as reactivity at high temperatures. Lawrence Livermore National Laboratory researchers published a review paper summarizing efforts to overcome these challenges.
