nanomaterials

1. Nanomaterials Alfa Chemistry offers a wide variety of nanomaterials, especially nanopowder and nanoparticle. If you do not find what you need please contact us. Nanomaterials can be defined as physical substances of which a single unit is sized (in at least one dimension) between 1 and 1000 nanometers (10−9 meter) but is usually 1-100 nm (the usual definition of nanoscale). Nanomaterials research utilizes nano-technology based on materials science methods, taking advantage of materials metrology and synthesis, which have been developed in support of physical and chemical manipulation for specific applications. Materials with nanostructures often possess unique optical, electronic, or mechanical properties. Figure 1. The structure of nanomaterials. The nanomaterials exhibit a fine structure Nanomaterials can be divided into four categories: nanopowder (nanoparticle), nanofiber, nanofilm and nanoblock. Nanopowder is the most mature technology, the basis to produce other three types of products. Nanopowder: Nanopowder also known as ultra-fine powder, generally refers to the powder or particles, the particle size of which is below 100 nanometers. The Nanopowder is a kind of solid particle in the middle state of atoms, molecules and macroscopic objects. Nanopowder can be used for high-density magnetic recording materials, absorbing materials, magnetic materials, radiation materials, monocrystalline silicon and precision optics polishing materials, micro-chip thermal substrate and wiring materials, microelectronics packaging materials, optoelectronic materials, High-toughness ceramic materials (throwing cracked

Nanofiber: Nanofiber refers to the diameter of the nano-scale and the length of the larger linear material. Nanofiber can be used for micro-wire, micro-fiber (important components used for quantum computers and photon computer materials in the future), and new laser or light - emitting diode materials. Nanomembrane: Nanomembrane is divided into granular membrane and dense membrane. Granular membrane is a thin film of nanoparticles that stick together with extremely small gaps in the middle. Dense membrane refers to that the film is dense but the grain size is in nano-scale. Nanomembrane can be used for gas catalysis materials (such as automobile exhaust treatment), filter materials, high- density magnetic recording materials, photosensitive materials, flat display materials and superconducting materials. Nanoblock: Nanoblock is a nanocrystalline material obtained by high-pressure nano-powder molding or controlling the crystallization of a metal liquid. The main purpose to use nanoblock is ultra-high strength materials and smart metal materials.
