What is Nanotexturing?
Nanotexturing refers to the process of modifying the surface of materials at the
nanoscale to achieve desired physical, chemical, or biological properties. This involves creating patterns or structures that are typically less than 100 nanometers in size. Nanotexturing can significantly alter the behavior of a surface, including its wettability, adhesion, and optical properties.
How is Nanotexturing Achieved?
Nanotexturing can be achieved through various techniques, including
lithography,
etching, and
self-assembly. Lithography uses light or electron beams to create precise patterns on a substrate. Etching involves removing material from the surface to create the desired texture. Self-assembly relies on the natural organization of molecules to form nanostructures.
