## Question

What are the advantages of conducting polymers?

## Short answer

Lightweight, flexible and cheaper than metals; easily processed into films and fibres; corrosion resistant; conductivity tunable by doping. They enable lightweight batteries, displays and sensors.

## Answer

Conducting polymers (such as doped polyacetylene and polyaniline) are light in weight, flexible and cheap compared with metals. They are easy to process and mould into films and fibres, they resist corrosion, and their conductivity can be controlled by doping. This makes them useful for lightweight batteries, displays and sensors.
