The investigation of interfaces in two-dimensional planar systems plays an elementary role in the investigation of porous hybrid materials, since it allows effects in more complex geometries to be attributed to their underlying causes. For the analysis of polypyrrole/silicon hybrid material systems, an electrochemical cell has been developed that enables the in-situ and nanometer-accurate investigation of the electropolymerization of pyrrole on planar silicon crystals using X-ray reflectometry. At the same time, electron density profiles and characteristic potential curves are recorded and layer heterogeneity is measured using SEM and AFM. The electrochemical cell enables the investigation of the voltage-induced swelling behaviour of polypyrrole, which opens up possible applications of porous polypyrrole/silicon hybrid material systems as actuators or sensors and optimizes them with regard to mechanical and electrical properties.
