NANOMATERIAL CLASSIFICATION

• INORGANIC
• Metallic complexes added to molten aluminum
• Particles surface active agents to modify
  structural, mechanical and surface properties of
  metals and alloys
• Thin films layers able to impart differentiated
  attributes to metals and alloys
• Interfacial control of oxide for durability and
  functionality

8
NANOMATERIAL CLASSIFICATION

• ORGANIC
• Nanoparticles in coatings
• Additives to coatings which enhance adhesion and
  durability of coated metals/alloys
• Optically clear additives that enhance scratch
  resistance lower surface energy
• UV stable pigments that yield more color-stable
  and durable coatings
• Nanomaterials in polymer film sheet
• Increase mechanical properties without
  sacrificing clarity or formability
