Interfaces in nanotechnology are the regions where two different materials or phases meet. These interfaces can be between a nanoparticle and its surrounding medium, between different layers in a thin film, or within a composite material. The properties of these interfaces are crucial as they can influence the overall behavior of the nanomaterial. For instance, the interface between a metal nanoparticle and a polymer matrix can affect the mechanical strength and thermal stability of nanocomposites.
