In this work, polypyrrole has been synthesized by microemulsion polymerization and was used to prepare the polypyrrole/activated carbon (PPy/AC) electrode. Particle size of PPy was controlled using different stirring speeds by homogenizer. The effects of particle size of PPy on electrochemical performance of PPy/AC electrode were investigated. The structural characteristics of PPy were determined by X-ray diffraction (XRD). The surface morphology was characterized by scanning electron microscope (SEM). The thermal properties of PPy were measured by differential scanning calorimeter (DSC). The electrochemical performance of PPy/AC was determined by cyclic voltammetry (CV) and galvanostatic charge/discharge characteristics in 0.5 M H2SO4 electrolyte. As a result, the specific capacitance of PPy/AC was improved with decreasing particle size of PPy. This was probably due to the high surface area and good conductivity of PPy.
