  2. What are Nano-Graphene Platelets (NGP)? • Similar to Carbon Nanotubes (CNT) • Graphene is a single atom thick sheet of carbon • Twice the surface area and qualities out perform nanomaterials • Outstanding conductor • Electron flow at high speeds, with virtually no collisions with atoms in the crystal Two sheets of graphene resting on top of a silicon dioxide substrate

  3. Characteristics • High Young’s modulus ~1,000 Gpa • Effective moisture barrier • Electrical conductivity similar to copper • Density is four times lower than copper • Thermal conductivity is five times that of copper • Essentially an opened up carbon nano tube. High surface area of ~2500m²/g • Has a lower density than steel but can be up to 50 times stronger

  4. Advantages • Mechanical, Thermal, electrical, chemical and adsorptive features • Chemical bonding to a lots of different resins • Can form oxygen, sulfur, hydrogen, and nitrogen sites • Able to filter harmful organic and non organic materials A cage constructed from graphene and nanotube pillars allows better hydrogen storage

  5. Uses for NGP • Battery electrodes and super capacitors • Fuel cells, solar cells and energy storage • Shield electromagnetic impulse and radio frequency for devices such as cell phones and computers • Aerospace: aircraft braking system, thermal management, and lightning strike protection • Automotive: fuel systems, tires, composites for internal an external parts • Filtrations and purification
