- Abstract
- Porous PEDOT-SiO2 particles were successfully prepared using simultaneous co-vaporized vapor phase polymerization (SC-VPP). By controlling the TEOS content, the morphologies of the obtained particles could be tuned from appearance of hollow egg shells aggregates to the hybrid particle composed of microspheres. Despite only having up to 40% of TEOS in the SC-VPP process, SiO2 accounts for over 90% of the resulting hybrid particle, because the hydrolysis/condensation reactions of TEOS would be much faster as compared with the PEDOT polymerization. The specific capacitance of a single hybrid particle decreased with increasing SiO2 portion, owing to changes in its external/internal structures.
