High pressure studies on one-dimensional (1D) carbon nanomaterials can provide deep insight into the new properties of carbon nanomaterials, which is also important for the fabrication of 1D superhard carbon nanomaterials. Here we present our recent research progress on high pressure studies of 1D carbon nanomaterials, including the results on structure stability, structure transitions and bonding change of fullerene nanotubes/nanorods, single-walled carbon nanotubes (SWNTs) and C60 filled SWNTs (C60@SWNTs) under pressure. The effect of nanosize and 1D nanoconfinement on the transformations of fullerenes under pressure is revealed. We also show how the structures of SWNTs transform under pressure, and further present the experimental evidence for the bonding formation of inter- and intra-tubes in compressed SWNTs.
