Nano-Graphene Platelets James Robbins MEEN 3344

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 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 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 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
