Nanomaterials<\/a>, as the name suggests, refer to materials with at least one dimension in the nanoscale range (1-100 nanometers). At this scale, materials exhibit distinctive properties compared to their bulk counterparts due to quantum and surface effects. <\/p>\n\n\n\n

Types of Nanomaterials<\/strong><\/h2>\n\n\n\n

The term “nanomaterials” became prominent in the 1980s when researchers began to explore the following materials at the nanoscale.<\/p>\n\n\n\n

    \n
  1. Carbon-Based Nanomaterials – <\/strong>Carbon-based nanomaterials are among the most extensively studied and widely used in nanotechnology. Graphene, a single layer of carbon atoms arranged in a 2D lattice, exhibits extraordinary mechanical strength, electrical conductivity, and thermal conductivity. Carbon nanotubes (CNTs), cylindrical nanostructures made of rolled graphene sheets, possess remarkable tensile strength and are valuable in various applications, including electronics and aerospace.<\/li>\n\n\n\n
  2. Metal-Based Nanomaterials <\/strong>– <\/strong>Metal-based nanomaterials encompass a diverse range of nanoparticles, such as gold, silver, iron oxide, and more.
