Free-standing films from chirality-controlled carbon nanotubes

Abstract Development of a method of formation of chiral free-standing films from carbon nanotubes (CNTs), which circumvents the limitations of the established techniques, is presented. CNT macroassemblies of any size and shape can be made from desired CNT feed including those synthesized or sorted with the objective of chirality control. Free-standing CNT films were created from various starting CNT materials the most interesting being of predominantly (6,5) and (7,6) chirality. The technique offers the advantages of technical simplicity, scalability and non-destructive nature representing an important step towards the research, development and implementation of monochiral single-wall CNT tangible objects.
