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

characteristics
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
advantages
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

uses for ngp
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
