Nanotechnology is the ability to create new materials, tools, and systems by controlling at the molecular and atomic levels and leveraging the properties that appear on their surfaces. From this simple definition, we can see that nanotechnology is not a new field, but a new approach in all fields. Nanotechnology involves understanding and controlling materials at dimensions of approximately ۱-۱۰۰ nanometers, and unique phenomena enable new applications. More specifically, nanotechnology is the imaging, modeling, and measurement of structures, devices, and systems with controlled manipulation of size and shape at nanometers (atomic, molecular, and polymer scales) that create structures. Design, characterization, manufacturing, and applications. The creation of powerful and intelligent fibers using nanotechnology has revolutionized the production of military fibers. These threads are about the same strength as the fibers used in bulletproof vests. They also have other important and valuable properties. Unlike traditional fibers and threads, these threads do not lose strength when weaving. These yarns maintain strength and flexibility even at very high temperatures and under unusual chemical conditions. Interestingly, various nanomaterials can also protect soldiers from bullets, shrapnel, and blasts. These materials contain channels filled with some kind of liquid that soldiers can easily move around. However, when hit by a bullet, the liquid changes its properties and hardens. As a result, the impact of the projectile causes only a slight impact.
