Smart Materials Flashcards
What are smart materials
Materials that respond to their surrondings, which adapt some way
What are the best smart materials
Those that respond to the situation and environment they are in the best. These materials function as both sensor and actuators
Talk about thermochromic materials
Materials thats pigments change with temperature
Talk about phosphorecent materials
Materials that glow in the dark
Talk about photochromic materials
Materials that change colour with the change in light intensity
Talk about electrochromic materials
Materials that change colour when voltage is applied
Talk about piezochromic materials
Materials that change colour with pressure
Talk about solvatochromic materials
Materials that change colour when dissolved
Talk about shape memory alloys
Made of nickle and titanium, when heated they return to shape
Talk about shape memory polymers
Polymers that can form under a change in stress or temperature
Talk about polymorph
A thermoplastic
Usually pellets
Mouldable when heated
Reusable
Talk about conductive paints
Paint sthat conduct electricity, a form of conductive material is set into the ink
Talk about smart and performance textiles
Textiles that are waterproof etc
motion control gels
uses the viscosity fo the liquid to control the sppedd at which objects pass through
hydrophobic materials
water repelent
oleophobi materials
oil resitant
self healing polymers
damage is healed when polymer cut etc eg cutting matts
self healing concrete
limestone producing bacteria are idcluded in teh conrete mix, water from a crack releases and the bacteria heal the crack
uses of themro chromic
room themometers
