Mesoporous porous polypyrrole-Ag nanocomposites for supercapacitors |
| 초록 |
Ultrafine polypyrrole-Ag nanocomposites were prepared by simple and one step aqueous (PPy-Ag-Aq) and interfacial (PPy-Ag-IF) polymerization methods. PPy-Ag nanocomposites were systematically characterized by FE-SEM, TEM, XRD and TGA confirming the formation of PPy-Ag nanocomposites and illustrated in Figure 1. From the FE-SEM analysis PPy-Ag-Aq nanocomposite was present in the highly porous form. TEM analysis shows the PPy-Ag-Aq nanocomposite present in the form of nanospindles (~30 nm) and nanospheres (~5 nm) form and PPy-Ag-IF nanocomposite present in the nanospheres form (~2-10 nm). PPy-Ag-Aq and PPy-Ag-IF nanocomposites were used study the applicability of the electrode material for supercapacitor by cyclic voltammetry and galvanostatic charge-discharge study. Mesoporous PPy-Ag-Aq nanocomposite was showing electrochemically more capacitive response than PPy-Ag-IF nanocomposite. |
