Abstract

A novel polypyrrole (a conducting polymer -PPy) potentiometric sensor suitable for environmental monitoring is described. It has been shown that it is possible to grow conductive polypyrrole-based polymers through a textile scaffold to create a flexible sensor that is robust enough to survive environments such as soil, with the choice of the scaffold material offering control of the environmental impact. Further work at University of Southampton has demonstrated that doped polypyrrole has an electrochemical response that is sensitive to different measurands’ concentration and in this case, we look at chloride response. Although this mechanism is designed for chloride sensitivity the principle can be made selective to specific ions (depending on dopant) in the future. The construction is advantageous because it is grown around the fibres (rather than printed on the top). It can also use the fibres as a support matrix and in principle could make individual fibres into sensing elements.
