NANOFIBERS Meaning and
Definition
-
Nanofibers are incredibly fine fibers with diameters at or below the nanoscale, typically measuring in the range of 1 to 100 nanometers. These fibers are synthesized through a variety of fabrication techniques, such as electrospinning or self-assembly processes, resulting in a highly structured and ultra-thin filamentous material. Nanofibers possess unique physical and chemical properties owing to their extremely small size, large surface area-to-volume ratio, and high aspect ratio.
Due to their distinctive characteristics, nanofibers find numerous applications in diverse fields, including materials science, biomedical engineering, environmental science, and energy production. In materials science, nanofibers are utilized to enhance mechanical properties and fabricate lightweight and high-strength composites. In biomedical engineering, their high porosity and similarity to the extracellular matrix make them ideal for tissue engineering scaffolds and drug delivery systems.
Nanofibers are also advantageous in filtration systems, as their small pore size and high surface area enable efficient removal of particles and contaminants from fluids. Additionally, nanofibers' conductive properties and large surface-to-volume ratio make them suitable for energy storage and catalysis applications. The versatility of nanofibers, along with their ability to be functionalized and integrated into various materials, makes them a promising material for technological advancements.
In summary, nanofibers are ultra-thin filaments with diameters in the nanoscale range, possessing unique physical and chemical properties. This material has found numerous applications across various fields, owing to its high aspect ratio, large surface area-to-volume ratio, and exceptional mechanical, electrical, and biological characteristics.
Etymology of NANOFIBERS
The word "nanofibers" is a combination of two parts: "nano-" and "fibers".
1. "Nano-" derives from the Greek word "nanos", meaning "dwarf" or "very small". It is used as a prefix in the International System of Units (SI) to represent one-billionth (10^-9) of a unit. In modern usage, "nano-" is generally associated with objects or phenomena at the nanoscale, which is the range of 1 to 100 nanometers.
2. "Fiber" comes from the Latin word "fibra", meaning "thread" or "filament". It refers to a slender and elongated structure with a high ratio of length to width, typically made of natural or synthetic materials.
When combined, "nanofibers" refers to fibers that have dimensions in the nanoscale range, i.e.
