Angstron Materials LLC has developed a new alternative to nanotubes, called nano-graphene platelets (NGPs).
Similar to carbon nanotubes, Angstron say that the properties and characteristics of NGPs outperform all other nanomaterials on the marke and is intended for aerospace, automotive, energy, marine, electronics, construction, medical and telecommunications applications.
The new material demonstrates thermal conductivity five times that of copper, a capability that provides fast thermal dissipation. NGPs also provide electrical conductivity similar to copper yet the material’s density is four times lower, resulting in lighter weight components.
Angstron say that they 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 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.
