• Smart Coatings and Materials

Materials, which are capable of adapting
dynamically their properties to an external
stimulus, are called responsive or smart.

• Smart Coatings and Materials

Most synthetic materials follow a permanently
defined path and behave statically The situation
is fundamentally different in biology Living
beings cope with continuous changes to
survive. - Reshaping, reorganization and
rebuilding-- bones - Dynamic and responsive
cell membranes

• Smart Coatings and Materials

• One-way systems Already in use
• -Corrosion sensing
• -Conductive coatings
• -Anti-inflammatory coatings
• Two-way systems More challenging
• -Shape-memory materials
• -Hydrophobic/hydrophilic switching
• -Thermochromic pigmented coatings

6

• Smart Coatings and Materials

• ? Adaptive materials
• -Properties endure as long as the signal is
  present
• -Permanent signal
• Switchable materials
• -Momentary signal

7
