Smart & Modern Materials

What is a smart or modern material?

A smart material is defined as one which is able to react to external stimulus / changes in the environment without human intervention (AQA )

A modern material has been engineered to have high tech properties but the material doesn’t ‘change’ in response to stimulus. 


Examples of smart materials

Thermochromic

Dyes that are micro encapsulated into fibres, yarns and fabrics which change colour in response to heat


Photochromic

Dyes that are micro encapsulated into fibres, yarns and fabrics which change colour in response to UV rays in light


Biomimicry 

  • Biomimicry refers to design that is inspired by how nature works
  • Speedo Fastskin is an example of biomimicry as the fabric and design are inspired by shark skin 
  • Stomatex is another example of biomimicry. It copies how a leaf transpires and releases body moisture through tiny domes with holes in, creating a breathable fabric


Examples of modern materials

Kevlar

Bullet proof vest
  • High performance aramid fibre (which means it is from the nylon family) that is very strong, lightweight, flame and chemical resistant and five times stronger than steel of the same weight
  • Used for bullet proof vests, to strengthen tyres, lining aircraft petrol tanks, safety gloves, skateboards, oil rig cables


Nomex

  • High performance aramid fibre that is flame and chemical retardant, durable, anti static, low shrinkage and resistant to oil
  • It is used for fire fighters clothing, racing driver suits, seating on public transport, oven gloves


Fluorescent fabrics

  • Fluorescent fabrics look ultra bright because of the way the colours absorb and emit light. UV rays react with the colour making them appear bright to the eye. Note that the colour itself never changes, it is just the way our eye sees them, which is why fluorescent fabrics are modern and not smart.
  • The colours appear brightest in low light and dull weather conditions. 


Reflective fabrics

  • Minute glass beads are embedded into yarns, fabrics, dyes and coatings
  • When light is shone on the surface the beads reflect light back into the viewer’s eye making the fabric appear shiny and bright
  • Note that the fabric itself never changes, it is just the way our eye sees them, which is why reflective fabrics are modern and not smart.
  • Reflective fabrics are often used for safety and protection e.g. uniforms, workwear, cycling wear
  • Reflective and fluorescent fabrics are often used together in products as both work in different types of light


Phosphorescent

  • Phosphorescent means ‘glow in the dark’
  • Phosphorescent pigments are micro encapsulated into yarns, fabrics, dyes, beads etc.
  • The pigments absorb UV light which is then released as a glow when there is no light around
  • AQA classify phosphorescent as modern although not everyone agrees with this. You should use AQAs classification when answering questions. 


Breathable fabrics

  • Breathable fabrics allow body moisture to evaporate away from the body. This process is called wicking. 
  • Gore-Tex is an example of a breathable membrane that is laminated between layers of fabric. It has microscopic  holes big enough to let body moisture through but too small for rain. 
  • Coolmax is another example of a breathable fabric. It works by moisture being wicked away through specially shaped fibres. 


For a summary of smart and modern materials, including additional ones to those listed above, look at AQA’s list 


Take care!

Be careful when using the classifications of smart and modern as there is some disagreement about which category some materials fit into. You are advised to use the classifications that AQA use on this sheet (or information provided by your own exam board) as although not everyone agrees with what it says this is how most exam questions are marked.

This is an area of textiles that is constantly changing with new technologies and products being developed all the time. Exam questions might refer to examples that are up to date so it is important you stay up to date with new materials. You should also be able to give up to date examples of your own to back up your answers. This is particularly the case at A level. 

You might use some of these high tech textiles products to help add detail to your answers:

 Suit worn by Pharrell Williams made out of 3M reflective fabric that looks like it changes colour when flash photos are taken

Tommy Hilfiger clothing with solar panels

Designer who works with wearable solar panels

Astroskin shirt that monitors astronauts health and how this has real world applicaitoions for people living in remote areas with doctors monitoring their health remotely

ThinkDo
  • Take photos of at least 2 products that use smart materials and 2 products that use modern materials
  • Explain why the examples you have chosen are considered smart and modern 
  • Use a diagram to explain how breathability works. Visit the Gore-tex website to find out more
  • Compare a non breathable product with a breathable one (e.g. a sports top). What are the differences in how it will feel to wear each product? Which will be more comfortable and why?
  • Summarise how smart and modern materials might add value to a product in the eyes of the consumer
  • Design a product of your own that uses smart or modern materials. Label your product to explain the technology that is used.
