Effect of Nanoparticle Size on Electrochemical Performance of Polypyrrole by Miniemulsion Polymerization |
| 초록 |
In this work, we synthesized polypyrrole (PPy) nanoparticles to evaluate their potential applicability as supercapacitor electrodes. The PPy was prepared by a miniemulsion polymerization process. The effects of nanoparticle size on electrochemical performance of PPy 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 was determined by cyclic voltammetry (CV) and galvanostatic charge/discharge characteristics in 6 M KOH electrolyte. As a result, the specific capacitance of PPy was improved with decreasing nanoparticle size of PPy. This was probably due to increasing surface area of PPy. |
