Enhancement of electrical conductivity and stability of polypyrrole by intercalation into montmorillonite
Original language description
Montmorillonite (MMT) was intercalated by electrically conducting polymer polypyrrole (PPYR) to obtain nanocomposites with enhanced electrical conductivity and stability in comparison with pure PPYR. Powder samples were prepared via oxidative polymerization of pyrrole in aqueous solution using oxidizing agent FeCl3. Two nanocomposites MMT/PPYR_1 and MMT/PPYR_2 containing 32 wt.% and 45 wt.% of PPYR, respectively, were prepared and characterized. Composition of the samples was studied using elemental analysis and XRFS, and amount of PPYR in each nanocomposite was calculated from TGA results. Intercalation rate was monitored by XRD. Raman spectroscopy was used to characterize the PPYR in the samples. Electrical measurements performed over 700 days revealed the course of changes in conductivity. Comparison of conductivities of samples showed enhancement of the conductivity and its preservation in the case of nanocomposites. The enhancement was observed throughout the whole testing period, the nanocomposites constantly exhibited higher conductivity compared to PPYR.
