| Abstract |
We report a new synthesis approach for precise control the wall morphologies of colloidal polypyrrole microparticles (PPyMPs) based on time dependent template-assisted polymerization technique. The resulting PPyMPs are water processable that allow simple and direct fabrication of multilevel hierarchical PPyMPs films for energy storage via a self-assembly process, whereas convention methods creating hierarchical conducting based on electrochemical polymerization are complicated and tedious. This approach allow the rational design and fabricate PPyMPs with well-defined size and tunable wall morphology, while the chemical composition, zeta potential and micro-diameter of the PPyMPs are well characterized. By precise controlling the wall morphology of the PPyMPs, we observed a pure nano-scale morphological effect of the materials on the energy storage performance. We demonstrated by controlling purely the wall morphology of PPyMPs to around 100 nm (i.e. thin-hollow PPyMPs), the thin-hollow PPyMPs show a typical supercapacitor characteristics with significant enhancement of charge storage performance up to 290% compared to thick-wall PPyMPs confirmed by cyclic voltametry, galvanostatic charge-discharge and electrochemical impedance spectroscopy. We envision the present design concept could be extended to different conducting polymers, as well as with other functional organic and inorganic dopants which provides an innovative model for future study and understanding on the complex physicochemical phenomena of energy-related materials. |
