Definition and classification of nanomaterials
Nanomaterials refer to materials with structural components at the nanoscale, typically ranging from 1 to 100 nanometers. Their small size yields distinct physical and chemical properties. These materials can be classified based on their dimensionality: zero-dimensional (like nanoparticles), one-dimensional (such as nanowires), two-dimensional (for instance, graphene), and three-dimensional structures. Different categories serve varied purposes in structural applications. Typically, nanoscale materials exhibit enhanced strength, lighter weight, and improved durability compared to conventional options.
