Characteristics of Nanomaterials:
Nanomaterials are materials with sizes
ranging from 1 to 100 nanometers in all three
dimensions. Their unique characteristics include:
• - Increased Surface Area: The surface of
nanomaterials plays a more significant role due to
the high surface-to-volume ratio, leading to
properties that differ significantly from larger
counterparts.
• - Quantum Effects: At the nanoscale, quantum
effects become dominant, influencing the physical
and chemical properties of the material.
• - Enhanced Properties: Nanomaterials can have
improved mechanical, electrical, magnetic, and
optical properties, making them valuable for
various applications.
