Nanocomposites are materials that combine nanoscale fillers with a matrix material to enhance their properties. These fillers can include nanoparticles, nanotubes, and nanofibers, which are typically dispersed within a polymer, metal, or ceramic matrix. The unique properties of nanocomposites, such as improved mechanical strength, electrical conductivity, and thermal stability, make them highly valuable in various applications, from electronics to biomedical devices.
