Carbon nanofibers provide an active and well‐defined high surface area material for electroanalytical processes. In this study a novel procedure is suggested for compacting carbon nanofiber (CNF) materials (diameter typically 100–200 nm) with a polystyrene (PS) binder and additives into highly conducting and re‐polishable CNF‐PS composite electrodes. Three types of carbon nanofibers (Pyrograf III, 70–200 nm diameter) and a range of compositions are surveyed. A 33 wt% carbon nanofibers in polystyrene electrode provides optimum electrical conductivity and reactivity.
