Nano Graphene Platelets (NGP) - 7nm x 25um
Nano Graphene Platelets are shaped like flat plates of ultra thin graphite. They have been found to have the following superior features:
Ultra-high Youngs modulus (approximately 1,000 GPa) and high strength (~ 100-400 GPa estimated). It is as stiff and strong as carbon nanotubes.
Exceptional in-plane electrical conductivity (up to ~ 20,000 S/cm).
Outstanding thermal conductivity (up to ~ 3,000 Wm-1@K-1).
Extraordinarily high specific surface area (up to ~ 2,675 m2/g).
Low density (2.25 g/cm3).
Outstanding resistance to gas permeation.
Readily Surface-Functionalizable.
Dispersable in many polymers and common solvents.
Available in a wide range of platelet lengths (typically 1-20 Fm) and thicknesses (approximately 0.34 nm to 100 nm).
High loading in nanocomposites.
Specifications:
Laboratory grade graphene nanoplatelets have about 5-25 microns in diameter and 5-10 nanometers thick. 100% carbon. This material ships as a dry powder. Each grade contains particles with a similar average thickness and surface area. All dimensions represent median sizes and there is a distribution with one standard deviation of about 20% of the mean.

Applications:
Similar to carbon nanotubes, the properties and characteristics of Nano Graphene Platelets NGPs should outperform all other nanomaterials on the market and is intended for aerospace, automotive, energy, marine, electronics, construction, medical and telecommunications applications.
Nano Graphene Platelets (NGP) demonstrate thermal conductivity five times that of copper, a capability that provides fast thermal dissipation. NGPs also provide electrical conductivity similar to copper yet the materials density is four times lower, resulting in lighter weight components.
In addition to superior mechanical, thermal and electrical properties, Nano Graphene Platelets (NGP) also possess unique chemical and adsorptive features, including: (a) good chemical bonding to a range of resins that enables tailoring of composite properties; (b) able to readily form reactive oxygen, sulfur, and nitrogen sites on graphene plate edges or surfaces; (c) capable of removing heavy metals and radionucleides from wastewater and ground water; and (d) highly adsorptive for organic materials. Due to these features, NGP-based nano materials may be used by customers in a broad range of industrial sectors to increase electrical conductivity, increase thermal conductivity and thermal stability, improve barrier properties, permit reduced component weight, increase stiffness, increase toughness (impact strength), improve appearance, including scratch resistance and they have flame retardant properties.
Application Examples:
Interconnect and heat dissipation materials in microelectronic packaging;
Electrodes in batteries and supercapacitors, and bipolar plates in fuel cells;
Automotive uses, including fuel systems (charge dissipation capability), tires (heat dissipation and stiffness enhancement), polymer composites, such as mirror housings, interior parts, bumpers, fenders, and body components that require electrostatic spray painting;
Aerospace applications, including aircraft braking systems (carbon/carbon composites), thermal management, EMI/RFI shielding, and lightning strike protection;
Environmental/chemical applications, including waste chemical/water treatments, filtration and purification; and
Electromagnetic impulse and radio-frequency shielding for telecommunications devices (e.g., mobile phones), computers, and business machines.
They have been used to make transparent electrically conductive coatings on solar cells, nano transistors that withstand much more heat than silicon transistors, materials to store hydrogen in fuel cell vehicles, anodes in lithium ion batteries and thousands of other possible uses.
