Effect of TiO 2 Rutile Additive on Electrical Properties of PPy/TiO 2 Nanocomposite
Polypyrrole/titanium dioxide nanocomposite (PPy/TiO 2 ) was synthesized by in situ chemical polymerization of pyrrole (Py) monomer in colloidal suspension of TiO 2 rutile. TEM and SEM images show that the TiO 2 is covered by PPy forming a core-shell structure. The PPy/TiO 2 core-shell will create n...

) was synthesized by
in situ
chemical polymerization of pyrrole (Py) monomer in colloidal suspension of TiO
2
rutile. TEM and SEM images show that the TiO
2
is covered by PPy forming a core-shell structure. The PPy/TiO
2
core-shell will create
n
-
p
junction and bring in an inversion layer on the PPy-shell surface. The feature is accounted for the modification in electrical properties of the PPy/TiO
2
nanocomposite. On the exposure to oxygen the conductivity of the nanocomposite exhibits an increase in 16–18-folds that are accounted for the interaction between oxygen (an electron acceptor) and the inversion layer. The cyclic voltammetry diagrams have shown that at around 15% TiO
2
and scan rate 100 mV/s the nanocomposites can reach a specific capacitance about 176 F/g. |
