• Nano Graphene Platelets (NGP) General Descriptions:

a) 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.

b) 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 material’s density is four times lower, resulting in lighter weight components.

c) Graphene manufacturing technology is divided into graphene synthesis, graphene film, and graphene complex. Graphene application device is divided into energy device, display device, electronic device, and BT-related device.

• Nano Graphene Platelet (NGP) Available Physical Size:
  
  Nano Graphene Platelets (NGP) can be produced as oxide free pristine NGP products in thicknesses ranging from 0.34 to 100 nanometers and widths of 0.5-20 microns in length.

• Nano Graphene Platelet (NGP) Typical Applications:

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. Application examples include:

(1) Interconnect and heat dissipation materials in microelectronic packaging;

(2) Electrodes in batteries and supercapacitors, and bipolar plates in fuel cells;

(3) 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;

(4) Aerospace applications, including aircraft braking systems (carbon/carbon composites), thermal management, EMI/RFI shielding, and lightning strike protection;

(5) Environmental/chemical applications, including waste chemical/water treatments, filtration and purification.

(6) Electromagnetic impulse and radio-frequency shielding for telecommunications devices (e.g., mobile phones), computers, and business machines. (7) Summary Statement: The primary advantage of these materials is their potentially high mobility (as seen in carbon nanotubes) and the ability to process in a planar form. The critical issues for graphene include the ability to:
     a. Deposit graphene over large areas with controlled grain size, thickness, and orientation
     b. Generate and control a bandgap in graphene
     c. Reduce or control surface and interface effects on charge transport
     d. Achieve a high mobility on a silicon compatible substrate
     e. Deposit a high κ gate dielectric with a high quality passivated interface
     f. Form reproducible low resistance contacts to graphene (contacting without etching through a monolayer film)
     g. Integration, doping and compatibility with CMOS

7) The preferred approach for deposition of graphene would be a CVD “like” process or epitaxial process on a silicon wafer; however other techniques could be used. Currently studied graphene deposition techniques include mechanical, chemical oxidation, or solvent exfoliation from highly oriented pyrolytic graphite (HOPG), direct CVD epitaxy on metal substrates, catalysed growth on silica or alumina, and sublimation of silicon from SiC. 

8) Cool electronic devices with a copper- graphene nanocomposite material.
