Study on the Microstructure of Inorganic Fullerene-Like WS2

The microstructure of the inorganic fullerene-like WS2 was analyzed by scanning electron microscope (SEM) and high-resolution transmission electron microscopy (HRTEM) in this work. The results indicate that the diameter of the WS2 particles is around 60~120 nm. The WS2 consists mainly of hollow polyhedral structures with quasi-spherical shape that is capable of sustaining much higher shock pressures due to a more uniform stress distribution on its surface. This characteristic made it a super shock wave absorbing material, which is great worth of bullet proof applications. This work is expected to develop a new type bullet-proof composite which can be used in the army.
