Abstract

The elastic behavior and structural changes of single-walled carbon nanotubes under hydrostatic pressure produced by a gasketed diamond anvil cell has been studied using in situ synchrotron x-ray diffraction. The compaction of the raft-like bundles of single-walled carbon nanotube showed a linear behavior up to 1.5 GPa pressure and the volume compressibility deduced from the experimental data is 0.024 GPa−1. The elastic deformation is attributed to the combination of a reduction in the inter-tubular distance and the polygonization of the otherwise circular nanotube sections.
