Nanomaterials can be categorized into four types [9, 10] such as: (1) inorganic-based nanomaterials; (2) carbon-based nanomaterials; (3) organic-based nanomaterials; and (4) composite-based nanomaterials. Generally, inorganic-based nanomaterials include different metal and metal oxide nanomaterials.
Similarly, What are the classifications of nanomaterials how it is classified?
Materials with one dimension in the nanoscale are known as Nanoplates. Nanoplates with two different longer dimensions are known as Nanoribbons. Based on the phases of matter contained by the nanostructured materials they are classified as nanocomposite, nanofoam, nanoporous and nanocrystalline materials.
Additionally, What are nanomaterials classify them with suitable examples? These nanomaterials include quantum dots, nanogold, nanosilver and metal oxides, such as titanium dioxide. A quantum dot is a closely packed semiconductor crystal comprised of hundreds or thousands of atoms, and whose size is on the order of a few nanometers to a few hundred nanometers.
