Lower reactivity can be achieved through several methods:
1. Surface Modification: By coating the surface of nanomaterials with inert substances or polymers, their reactivity can be significantly reduced. 2. Doping: Introducing small amounts of other elements into the nanomaterial can alter its electronic properties, making it less reactive. 3. Size and Shape Control: The size and shape of nanoparticles can influence their reactivity. Smaller particles with high surface area tend to be more reactive, so controlling these parameters can help reduce reactivity.
