Chemistry of Engineering Materials

Nanomaterials are materials that have dimensions on the nanoscale, typically ranging from 1 to 100 nanometers. They have different properties compared to bulk materials due to their large surface area to volume ratio, which can lead to changes in their optical, electrical, mechanical, and catalytic properties.

The size of nanomaterials is significant because it affects their properties. As the size decreases, the surface area to volume ratio increases, leading to enhanced reactivity and unique properties.

Nanomaterials can be classified based on their composition, shape, and dimensions. Common classifications include nanoparticles, nanowires, nanotubes, and nanostructured materials.
