Applications of Nanomaterials and Nanotechnology in Military and Aerospace Fields

Nanomaterials refer to ultrafine materials whose grain size is on the order of nanometers (1–100 nm). When the particle size of the material is in the nanometer state, its molecular arrangement, electron distribution and crystal structure change, which is very different from the usual bulk materials in terms of structure and performance. The main four physical effects of nanomaterials include: surface effect, small size effect, quantum size effect and macroscopic quantum tunneling effect.
