Nanotech in Manufacturing Outline


How to Manufacture

Nanotechnology1. Top Down technique uses large

machines to make the nanostructures from larger materials

• Example: Photolithography to make Computer Processor Chips

2. Bottom Up technique uses chemical and physical interactions

to make nanostructures without guidance

• Example: Catalyst to make Carbon Nanotubes

3. Smart Materials are manufactured goods that react to some outside forces. Crystals can expand and contract with electricity, metals can retain a shape memory, liquids can move with magnetic fields, and surface cracks can heal themselves.

cc by Thomas Shahan


Self-Healing Materials have micro- or nano-size capsules of chemicals in the structure. When a crack forms, it ruptures the capsules, releasing the chemicals to react and heal the material.

Products can now heal themselves.

Ferro Fluids are liquids with nanoscale magnetic particles suspended. This makes the

whole fluid react to a magnetic field but turn back

into a liquid without it.

4. Nanotubes and buckyballs are nanoscale carbon structures that hold many useful properties for manufacturing and products.

Carbon Nanotubes

• Are stronger than steel• Can be made to be very conductive• Can be made to be nonconductive• Are good heat conductors in one direction• Are good heat insulators in the other direction

cc by Guillaume Paumier


• Carbon nanotubes are put on glass to make it electrically conductive. The glass stays clear because the nanotubes are so small.
