The exceptional performance of nanomaterials, as a result of their size and
unique morphology, has attracted a lot of researchers. The structure and constituents of
materials have been modified using a variety of techniques. The ion beam techniques
have so far been widely employed to modify the performance of different
nanomaterials. The surface configuration and chemical composition of nanomaterials
can be altered by energetic ion beams. The ion beam techniques approach is purely
physical in comparison to conventional methods. These techniques exhibit outstanding
control and reproducibility without adding any impurities to the target materials. Here,
current developments in surface modification of nanomaterials employing ion beam
methods are thoroughly reviewed.
