Smart material types include piezoelectric polymers, conductive polymers, piezoelectric and electrostrictive ceramics, electrorheological fluids, magnetorheological fluids, electrochromic coatings, magnetostrictive materials, micromachined integrated devices, and biomimetic polymers and gels, shape memory alloys and polymers.

But I thought, no, no, experiment with resins, experiment with polymers.

In our world we use about 350 polymers to make all this.

Natural polymers, well ... I think that's what's most important, because these polymers have been tried and tested in our ecosystem for the last billion years, in everything from mushrooms to crustaceans.

We use five polymers in the natural world to do everything that you see.

This is made bone is made from a mixture of inorganic minerals and polymers.

And also, I thought that there would be synthetic polymers, plastics, embedded in the rock.

When that moves into polymers, you can change the elasticity, the fluidity of the form.

79. Conductive polymers can change colour and conductivity in response to chemical and electronic stimuli.

The revised proposal was sent again for evaluation, and now the reviewers reason for rejecting it was that new polymers would not be safe to test on animals or people. Another graduate student showed that the polymers were safe.

Shape memory polymers are commercially available in a number of convenient physical states, including pellets, solutions and liquids.

Yet one of my graduate students synthesized the polymers for his doctoral thesis. We sent the proposal back for another review, only to be told that the grant should still not be funded, because the polymers would react with whatever drug we wanted to deliver.

Supramolecular assemblies 82. Both natural and synthetic polymers can be designed to form large assemblies of molecules with useful properties.

Fossil fuels are also essential for the creation of plastics and polymers, key ingredients in computers, entertainment devices and clothing.

Although biomimetic polymers and gels are currently at the research and development stage, future use as biosensors and neural prostheses is possible.

78. Shape memory alloys and polymers can return to their original shape upon being heated to a higher temperature after being shaped under thermomechanical conditions.

If this behaviour can be understood and extended to common commodity polymers, such nanocomposites could compete effectively with higher priced engineering plastics and find widespread application.
