Technologically Relevant Applications

Carbon nanothreads hold significant promise for potential applications in view of their ultralight density and superior elastic properties. This chapter aims to introduce the functionality of carbon nanothreads and compare the performances with respect to other nanomaterials. The computational details of molecular dynamics simulation are introduced. The sensitivity and energy dissipation factor of various carbon nanothreads are investigated, and it is demonstrated that carbon nanothreads are excellent resonators with ultrahigh sensitivity and low dissipation. Carbon nanothreads membrane is demonstrated as an outstanding gas membrane with strain-dependent selectivity, and exhibit very high permeabilities of gas molecules. Carbon nanothreads also allow full mechanical energy storage through pure tension, which indicates that they are promising building blocks for energy storage devices.
