NANOMATERIALS
Ziad zohdy
What is nanomaterial
• Nanomaterials are commonly defined as
materials with an average grain size less than 100
nanometers
• Nanomaterials have extremely small size which
having at least one dimension 100 nm
• One billion nanometers equals one meter
• The average width of a human hair is on the order of
100,000 nanometers
• A single particle of smoke is in the order of
1,000 nanometers
Nanomaterial shapes
• nanomaterials can be nanoscale in
one dimension ( surface films )
• Two dimensions ( strands or fiber)
• Three dimensions ( particles )
• They can exist in single or fused
forms with spherical, tubular, and
irregular shapes.
Why nanomaterials ?
• Nanotechnology exploits benefits of ultra
small size, enabling the use of particles to
deliver a range of important benefits
– Small particles are ‘invisible’ :
• Transparent Coatings/Films are attainable
– Small particles are very weight efficient:
• Surfaces can be modified with minimal material
• the behavior of nanomaterials may depend
more on surface area than particle
composition itself.
• Relative-surface area is one of the principal
factors that enhance its reactivity, strength
and electrical properties.

  • 2. What is nanomaterial • Nanomaterials are commonly defined as materials with an average grain size less than 100 nanometers • Nanomaterials have extremely small size which having at least one dimension 100 nm • One billion nanometers equals one meter
  • 3. • The average width of a human hair is on the order of 100,000 nanometers • A single particle of smoke is in the order of 1,000 nanometers
  • 4. Nanomaterial shapes • nanomaterials can be nanoscale in one dimension ( surface films ) • Two dimensions ( strands or fiber) • Three dimensions ( particles ) • They can exist in single or fused forms with spherical, tubular, and irregular shapes.

  • 7. Weight efficient and Uniform coverage • Large spherical particles do not cover much surface area • Nanoparticles Equal mass of small platelet particles provides thorough coverage (1 x 106 times more)
  • 8. • by patterning matter on the nano scale, it is possible to vary fundamental properties of materials without changing the chemical composition
  • 9. Approaches • Top-down – Breaking down matter into more basic building blocks. Frequently uses chemical or thermal methods. • Bottoms-up – Building complex systems by combining simple atomic-level components.
  • 10. Methods for creating nanostructures • Mechanical grinding example of ( top-down ) method • Wet Chemical example of both ( top-down) & ( bottom up )
  • 11. • Sol-gel process Methods for creating nanostructures
  • 12. • Gas Phase ( furnace ) Methods for creating nanostructures
  • 13. Different types of Nanomaterial • Nanopowder • Nanotube : tiny strips of graphite sheet rolled into tubes
  • 14. Why are nanomaterials important • These materials have created a high interest in recent years by their high mechanical, electrical, optical and magnetic properties. Applications of nanomaterials • nanophase ceramics • nanostructured semiconductors • Nanosized metallic powders • Single nanosized magnetic particles • Nanostructured metal-oxide thin films
