Model of a carbon nanotube
Carbon Nanotubes
• 100 time stronger than steel and very flexible
• If added to materials like car bumpers, increases strength and flexibility

Materials: Paint That Doesn’t Chip
• Protective nanopaint for cars– Water and dirt
repellent– Resistant to chipping
and scratches– Brighter colors,
enhanced gloss– In the future, could
change color and self-repair?

Materials: Stain Resistant Clothes
• Nanofibers create cushion of air around fabric– 10 nm carbon whiskers bond with cotton – Acts like peach fuzz; many liquids roll off

Environment: Paint That Cleans Air
• Nanopaint on buildings could reduce pollution– When exposed to
ultraviolet light, titanium dioxide (TiO2) nanoparticles in paint break down organic and inorganic pollutants that wash off in the rain
– Decompose air pollution particles like formaldehyde
Buildings as air purifiers?

Technology: A DVD That Could Hold a Million Movies
• Current CD and DVD media have storage scale in micrometers
• New nanomedia (made when gold self-assembles into strips on silicon) has a storage scale in nanometers– That is 1,000 times more storage along each
dimension (length, width)…

…or 1,000,000 times greater storage density in total!
