Conducting polymers (CPs) are discussed in a huge variety of electronic devices including electrochromic windows, batteries, actuators and chemical-biology sensors, mainly because of switchable electronic and optical properties. Compared to other conducting materials, CPs have advantages of light-weight, low cost, non-toxicity, flexibility, easy processing, and low voltage operation. In our group, poly(3-hexylthiophene) (P3HT) and poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) are mostly studied. In the case of P3HT, the doping states can be precisely controlled by electrochemical or chemical doping, which results e.g. in an increase of conductivity over 6 orders of magnitude with a maximum of 224 S/cm. [1] On the other hand, PEDOT: PSS can be controlled by electrochemical means, but also by humidity, as used e.g. for actuators. [2] In this contribution, we will show our preliminary data on the wetting behavior on such switchable and adaptive CP surfaces.
