Carbon nanotubes (CNTs) exhibit outstanding mechanical and electrical properties. However, CNT fibers (CNTFs) have still problems in realizing these properties because of the weak forces between nanotubes with many defects of individual CNTs. Here, w

Weak van der Waals forces between inert hexagonal boron nitride (h-BN) nanosheets make it easy for them to slide over each other, resulting in an unstable structure in macroscopic dimensions. Creating interconnections between these inert nanosheets c
