Nanomaterials are materials where at least one dimension of the structure is in the nanoscale (1-100 nm). For example, nanomaterials are called nanofilms or lamellar if the nanoscale occurs in only one dimension, strands, wires or fibers if nanoscaled in two dimensions, and nanoparticles if nanoscaled in three dimensions. Nanocomposites/nanoalloys are when nanoparticles are mixed into a polymer or metal matrix
