Due to weak interaction among phosphorus atoms in black phosphorene, the nanotube obtained by curling single-layer black phosphorus is not as stable as a carbon nanotube (CNT) at finite temperature. In the present work, we recommend a new 1D composite material with a double-wall nanotube (DWNT) from a black phosphorus nanotube (BPNT) and a CNT. The dynamic response of the composite DWNTs is simulated using molecular dynamics approach. Effects of factors including temperature, slenderness and configurations of DWNTs on dynamic behavior of the composite are discussed. Comparing with a single-wall BPNT, the composite DWNTs under uniaxial compression shows some unique properties. When the BPNT is embedded in a CNT which will not only isolate BPNT from the ambient condition, but also improve the capability of axial deformation of BPNT, the system will not collapse rapidly even if the BPNT has been buckled.  Read more
