Understanding Nanomaterials

Nanomaterials Definition

Nanomaterials refer to materials with at least one dimension between 1 and 100 nanometers. This scale grants them unique properties in various domains such as optics, electronics, thermophysics, and mechanics.




Classification of Nanomaterials

Engineered Nanomaterials

These are intentionally crafted materials, engineered by humans to exhibit specific properties, opening new avenues in various industries.

Legacy Nanomaterials

Materials that predate deliberate nanotechnology development but possess nano-level characteristics. Examples include carbon black and titanium dioxide nanoparticles.

Incidental Nanomaterials

Unintentionally generated through industrial processes like combustion and vaporization, including vehicle emissions and smelting byproducts.

Natural Nanomaterials

Occurring in biological systems or through natural phenomena, such as viruses, wax crystals, and volcanic ash. They encompass both organic and inorganic substances, showcasing diverse nanostructures.

Characteristics and Categorization

Nano-object Dimensions

Defined by the number of external dimensions falling within the nanoscale, including nanoparticles, nanofibers, and nanoplates, each with distinct dimensional attributes.

Nanostructured Materials

Categorized by the phases they encompass, such as nanocomposites, nanofoams, nanoporous materials, and nanocrystalline materials, each possessing unique structural compositions and properties.

Nanomaterials, with their intricate structures and exceptional properties, hold immense potential across industries, from electronics to healthcare, ushering in a new era of innovation and commercialization.
