Sensor technology, electrically active polymers

PPy offers tremendous technological potential, especially as electrodes for rechargeable batteries, sensors or supercapacitors. Since the electrochemical activity of PPy electrodes is proportional to the surface area, they must be processed to a shape in which the ratio of the surface area to volume or weight is high. This feature could be obtained via converting PPy to a fibre with small diameter, i.e., a nanofibre. In the nanoscale, the electrical conductivity of conductive polymers is increased.
