Materials in the Future |
Smart Materials Nanoengineered Materials |
|
Semiconductors |
have electrical properties that are intermediate between the electrical conductors and insulators |
|
Biomaterials |
are employed in components implanted into the human body for replacement of diseased or damaged body parts. |
|
Smart Materials |
are a group of new and state-of-the-art materials now being developed that will have a significant influence on many of our technologies. |
|
Nanoengineered Materials |
These materials often have unique optical, electronic, or mechanical properties |
|
Main Groups of Smart Materials |
Color Changing MaterialsLight Emitting MaterialsMoving MaterialsTemperature Changing Materials |
|
Color Changing Materials |
These are materials that change color due to different external stimuli |
|
Photochromic materials
|
It change reversibly color with changes in light intensity. |
|
Thermochromic materials |
Change reversibly color with changes in temperature. |
|
Light emitting materials |
These are materials that change the light in some sense, due to some external stimuli. |
|
Electroluminescent materials |
produces a brilliant light of different colors when stimulated electronically |
|
Fluorescent materials |
produce visible or invisible light as a result of incident light of a shorter wavelength |
|
Phosphorescent materials or afterglow materials |
produce visible or invisible light as a result of incident light of a shorter wavelength (i.e. X-rays, UV-rays, etc.),detectable only after the source of the excitement has been removed |
