The mechanical property of carbon nanocoil

Benefiting from their unique nanoscale spiral morphology and large aspect ratio, carbon nanocoils (CNCs) show outstanding stretchable ability and vibratory property. Based on material mechanics, the quantitative relationships between the elastic coefficient and lateral stiffness of CNCs and their geometric parameters are revealed. Moreover, it is found that the crystallinity of CNCs plays an important role on their mechanical properties, which is confirmed by Raman spectroscopy test. The theoretical derivation and experimental analysis on the mechanical property of CNCs provide a foundation for their synthesis regulation and potential applications.
