What is the difference between nanoparticles and nanocomposites?

Nanoparticles and nanocomposites are both types of nanomaterials but possess distinct characteristics. Nanoparticles, as the name suggests, are tiny particles with dimensions ranging from 1 to 100 nanometers. These particles have a uniform composition and can be made from metals, oxides, or organic compounds. Nanoparticles often exhibit unique physical and chemical properties due to their small size. On the other hand, nanocomposites are materials composed of nanoparticles dispersed within a matrix material. The matrix can be a polymer, metal, or ceramic. The addition of nanoparticles enhances the properties of the matrix material, leading to superior mechanical, electrical, or thermal characteristics. Nanocomposites often exhibit a synergistic effect, where the overall performance is greater than the sum of the individual components. In summary, nanoparticles refer to individual nanoscale particles, while nanocomposites involve the dispersion of nanoparticles into a matrix material, resulting in enhanced performance and improved properties.
