The radial mechanical properties of single‐walled boron nitride nanotubes (SW‐BNNTs) are investigated by atomic force microscopy. Nanomechanical measurements reveal the radial deformation of individual SW‐BNNTs in both elastic and plastic regimes. The measured effective radial elastic moduli of SW‐BNNTs are found to follow a decreasing trend with an increase in tube diameter, ranging from 40.78 to 1.85 GPa for tube diameters of 0.58 to 2.38 nm. The results show that SW‐BNNTs have relatively lower effective radial elastic moduli than single‐walled carbon nanotubes (SWCNTs). The axially strong, but radially supple characteristics suggest that SW‐BNNTs may be superior to SWCNTs as reinforcing additives for nanocomposite applications.
