There are many varieties of intentionally-produced nanomaterials. More are on the horizon.
Types of Nanomaterials
For this article’s purposes, the most current nanomaterials could possibly be divided into 4 types.
Material that is carbon-based
-Metal Based Material
-Dendrimers
-Composites
Material Based on Carbon
These nanomaterial are mostly composed of carbon. Most often, they take the forms of hollow tubes, ellipsoids, and spheres. Fullerenes is a term for ellipsoidal, cylindrical and sphere-shaped carbon nanomaterials. These nanomaterials have potential uses in electronics.
Metal Based material
The nanomaterials are nanogold, quantum dots and nanosilver. A quantum dot can be described as a highly packed semiconductor crystal containing hundreds to thousands of individual atoms. The size ranges between a few micrometers and several hundred nanometers. You can change the optical properties by changing quantum dots’ size.
Dendrimers
These nanomaterials, which are made from nanosized polymers and branched-unit polymers, can be called nanomaterials. Many chain ends can be added to a dendrimer’s surfaces, which allows them to carry out specific chemical functions. This characteristic could be helpful for catalysis. The three-dimensional density of dendrimers has interior cavities, which could allow for other molecules to be placed. This may make them suitable for drug delivery.
Composites include nanoparticles mixed with others or larger bulk-type materials. Products such as auto parts and packaging materials are featuring nanoparticles like nanosized clays to increase their thermal, flame-retardant, and barrier properties.
Unique Properties
Because of their unique characteristics, these nanomaterials can be used in many different applications, including medical, military, commercial and environmental. You may also see these materials in complex nanostructures. This is because of the many products that have these nanomaterials, as well as their potential applications.
The material’s shape can help you to distinguish between four different types of materials: nano-particles materials, nanosolid materials, and nanofilm materials.
Material made of nano-particles. This refers to the direct use of these nano-particles. Ultra-fine particulate catalysts (also known as fourth generation catalysts) can greatly improve catalytic effectiveness by using high specific surface areas and very active. In order to increase organic compound chlorination efficiency by 10 times, ultrafine Ni- and Steel-Zinc Alloy catalysts may have particle sizes that are less than 0.3 microns. The catalyst can help carbon dioxide to be converted into carbon and water with low temperatures. Ultrafine iron powder is a potential nucleator role in the thermal gas phase decomposition benzene that forms carbon fibers.
Magnet particles are used for magnetic recording media, such as disks, tapes, or videotapes. Due to the increase in informationization, high amounts of information storage, and speedy information processing, are necessary. As a result, the magnetic particles that can be used for magnetic record tends to get smaller. Metal magnetic powders are used to make metal tapes and metal disks. Their recording density is between 409 and 4107 bits per centimeter, which is 107 or 108 bits/inch. They are capable of recording anywhere from 4,000,000 to 40,000,000 information units every centimeter. They can record more information per centimeter than normal tapes but have low noise. There are other benefits such as high signal-to–noise ratios.
It is important to note that nano-solids have very large intergranular interactions. If 5 nano-particles were combined, the solid would contain 1019 grain boundaries/cm2. The atomic diffusivity of the material is 1014-1016 times that of bulk materials. Nano-materials also have high toughness. Ceramics generally have the benefits of being hardened, resistant to wear, corrosion and durable, but also the disadvantages of being fragile and challenging to process. There are nano-ceramics that can boost toughness, and even improve brittleness.
