Abstract
Conducting polymers are widely researched in terms of both their electrical and optical properties. The optical properties are typically observed on the macroscopic scale. To broaden their application, fabrication and char-acterization of conducting polymers on the nanoscale thickness are required. In this study microscale volume poly(3,4-ethylenedioxytiophene)-Tosylate (PEDOT:Tos) layers are fabricated at the tip of a single mode optical fibre without the need for intermediate layers such as Indium Tin Oxide. This allows for optical interrogation (primarily at 1550 nm) of the properties and behaviour of PEDOT:Tos below thicknesses of 500 nm. The optical response (transmission and back-reflection) of the PEDOT:Tos obtained by exposure to different oxidant solu-tion is measured. The effect of different oxidant solution on conductivity, thermal conductivity and degradation time will be examined. This knowledge will lead to implications for the use of conducting polymers in sensing applications where an optical response is detected via a fibre.
