What are nano graphene platelets ngp

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
