Nanoscale Hollow-Bubbly Polypyrrole Obtained via Interfacial Polymerization with Phase Transfer Catalyst

Abstract:

Crown ether 18C6 was used as a phase transfer catalyst (PTC) for the interfacial polymerization of polypyrrole (PPy). Usually, in interfacial reacting system, oxidant FeCl₃ was dissolved in deionized water to form aqueous phase, while pyrrole was dissolved in chloroform to form organic phase. The 18C6 PTC can efficiently form complexes with Fe (III) and transfer Fe (III) from aqueous phase into organic phase, resulting in nanoscale hollow-bubbly PPy with better electronic properties. UV-vis was used to confirm the phase transfer ability of composed Fe (III). Cyclic Voltammograms (CVs) were used to characterize capacitance property of PPy. Fourier Transition Infrared (FT-IR) spectroscopy and Scanning Electronic Microscopy (SEM) were carried out to investigate the microstructure of PPy. Finally, defect control migration growth mechanism of PPy during the polymerization has been carefully discussed.
