Nanocomposites refer to the combination of two or more materials at the nanoscale level, where at least one of the materials has unique properties due to its small size. It has become a specialized skill as it requires knowledge and expertise in nanotechnology, materials science, chemistry, physics, and engineering. Nanocomposite materials have numerous applications in various fields, including medicine, energy, electronics, and environmental science. The successful fabrication of nanocomposites requires the use of advanced techniques and sophisticated instruments, making it a highly specialized and technically demanding field.
