Chapter 11- Manipulating And Combining Materials Flashcards
Light – emitting materials
Electroluminescent- emergency exits, electric current passed through
Fluorescent materials produce light when exposed to UV rays
Phosphorescent materials produced light as a result of being exposed to a light source. Only after light source removed
Modern materials
Those that have been developed over the past 50 years
Mixture of materials- composites
Carbon fibre, fibre optics, waterproof and breathable
Kevlar- same weight as steel but even harder, plastics
PCL- low melting point, biodegradeable, morphed by hand modelled
Smart materials- colour changing
Photochromic- change colour in responsive to light
Thermochromic – change colour in response to changes in temperature
