A modern material is...

a material that has been recently developed for specific applications.

a material that reacts to a stimulus

a material invented since the year 2000

a material with useful properties

These materials react and change with a physical change in their environment e.g. heat, light, electrical current.

Smart Materials

Modern materials

Nano materials

New Materials

I am a smart material that is easily bent when cool but jump back into shape when heated above a certain temperature eg. nitinol

Shape memory Alloys

Nano Materials

Ceramics

Cornstarch polymers

Materials that use small particles to give them cool properties:
-they have medical uses(antibacterial fabrics)
-Self cleaning fabrics

Smart Materials

Nano materials

Modern Materials

Super alloys

Respond to changes in temperature by changing colour, t-shirts, mugs and temperature strips

Nanomaterials

Thermochromic materials

Integrated electronics

Thermochronic Materials

Amazing strength to weight ratio and is easily moulded/shaped. Resistant to corrosion, rigid/stiff and quite expensive.

Kevlar

Carbon fibre

GRP

Tungsten

Glow in the dark, absorbs light during the day and emits it when dark E.G Fire exit signs

Photochromic Materials

Thermochromic Materials

Phosphorescent pigments

Holograms

These are made from either natural polymers (from plant products such as corn starch) or they use these materials to mix with normal plastics to make them break down faster.
.

Smart materials

Biodegradable Plastics

Phosphorescent pigments

Metallic foams

They change colour depending on the amount of light hitting the surface. By far the most common use of this is in light-sensitive glasses, such as sunglasses.

Reflective Films

Phosphorescent pigments

Holograms
