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
