Angstron nano-graphene platelets

Angstron's new nano-graphene platelets have been developed as a cost-effective alternative to nanotubes.

Angstron Materials LLC (Dayton, Ohio) announced on April 21 that it has developed what is said to be a 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 reportedly outperform other nanomaterials on the market. Angstron's nano-graphene product is designed for aerospace, automotive, energy, marine, electronics, construction, medical and telecommunications applications.

The new material has thermal conductivity five times than that of copper, a capability that provides faster thermal dissipation. NGPs also provide electrical conductivity similar to copper, but at a density four times less. NGPs are said to be 50 times stronger than steel with a surface area twice that of carbon nanotubes.

Angstron can produce oxide-free pristine NGP products in thicknesses ranging from 0.34 nm to 100 nm in widths of 0.5 micron to 20 microns. 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 reportedly can achieve 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 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.
