Study Notes
Engineered Nanomaterials
- Engineered nanomaterials are materials with at least one dimension between 1 and 100 nanometers.
- They possess unique physical and chemical properties that offer functional advantages.
Classification of Nanomaterials
- Nanomaterials can be classified based on the number of dimensions not confined to the nanoscale.
- Zero-dimensional (0D) nanomaterials: All dimensions are within the nanoscale, and no dimension is larger than 100 nm.
- One-dimensional (1D) nanomaterials: One dimension surpasses the nanoscale. Examples include nanotubes, nanorods, and nanowires.
- Two-dimensional (2D) nanomaterials: Two dimensions exceed the nanoscale. Examples include nanofilms, nanolayers, and nanocoatings.
- Three-dimensional (3D) nanomaterials: All three dimensions extend beyond the nanoscale. Also known as bulk nanomaterials.
