Angstron Introduces Low Cost Graphene Platelets
(Nanowerk News) Angstron Materials LLC has developed a new cost effective, high quality alternative to nanotubes. The carbon-based material is called nano-graphene platelets (NGPs). Similar to carbon nanotubes, the properties and characteristics of NGPs outperform all other nanomaterials on the market. Angstron’s nano-graphene product is especially suited to aerospace, automotive, energy, marine, electronics, construction, medical and telecommunications applications.
The new material demonstrates the highest thermal conductivity known today, five times that of copper, a capability that provides faster thermal dissipation. NGPs also provide electrical conductivity similar to copper yet the material’s density is four times lower, resulting in lighter weight components. NGPs are fifty times stronger than steel with a surface area twice that of carbon nanotubes. These exceptional performance characteristics equip customers with the capability to modify and create new products with the potential to achieve competitive advantage and generate higher profit margins.
Angstron can produce oxide free pristine NGP products in thicknesses ranging from 0.34 to 100 nanometers and widths of 0.5-20 microns in length. Exceptionally high length-to-thickness aspect ratios of up to 10,000 are available. In addition, Angstron can modify the chemistry of the nano-platelet surface to fine-tune electrical, thermal, mechanical, optical, magnetic, chemical and other key performance properties while maintaining precision control of platelet dimensions and other physical parameters.
Angstron’s engineered NPGs are available in several forms including raw materials and solutions. These solutions can achieve an exceptionally high loading and maintain uniform dispersion without degrading viscosity. Angstron’s NGP product can be blended with other nanomaterials to achieve higher loadings required for various forms of composite lamina as well as nanocomposites for load-bearing and functional applications.
Angstron’s skilled team can also tailor nanomaterial products to customers’ manufacturing processes, enhanced materials or device needs. The advanced materials specialist offers customers a total turnkey solution from application development and pilot quantities for test articles to scale-up for required production volumes. Angstron is currently working with companies to develop products for batteries, fuel cells, supercapacitors, light weight structural components as well as electromagnetic interference (EMI), radio magnetic indicator (RMI), electrostatic discharge (ESD), lightning strike and composite applications.
Angstron Materials LLC leads the industry as the first advanced materials company to offer large quantities of single atomic layer thick nano-graphene platelets (NGPs). Committed to equipping customers with the tools they need to compete, Angstron is also reducing production cost barriers with its nano-graphene solutions. NGPs are similar to nanotubes but offer improved performance properties including very high Young’s modulus, strength and surface area, superior thermal and electrical conductivity, lower density and less weight. NGPs are also resistant to gas permeation. As a result, Angstron is able to work with companies to develop products for batteries, fuel cells, supercapacitors, light weight structural components as well as electromagnetic interference (EMI), radio magnetic indicator (RMI), electrostatic discharge (ESD), lightning strike and composite applications.
In addition to its ability to provide sample materials and scale-up, Angstron partners with customers to help manufacturers identify optimal designs, compositions and manufacturing processes. Available in a wide range of geometries, NGP products are easily surface functionalizable for polymer and common solvent applications and offer high loading potential for nanocomposite applications. Angstron combines real world experience with research and development to help manufacturers harness the advantages of nanotechnology to make next generation products in the aerospace, automotive, energy, marine, construction, electronics, medical, and telecommunications markets.
