| الملخص: | Conducting polymer materials based on Polypyrrole (PPy) and
Polypyrrole/Montmorillonite (PPy/MMT) clay composite were synthesis by using
chemical reaction process with iron (III) chloride (FeCl3) as oxidizing and dopant agent.
During the mixing process of PPy, the solution changed from transparent to dark green
indicating that the polymerization process took place instantaneously. The resulting
powder was filtered, washed, grounded and press into pellet. The structural, thermal and
electrical properties of the conducting polymer and conducting polymer composite were
then investigated.
The structure of the samples was analyzed by using X-ray diffractometer (XRD) with
the scanning was carried out at 2θ of 15° to 35° for doped PPy and at 2θ of 2° to 35° for
PPy/MMT clay composite. The XRD spectra showed dopant and filler effect with appearance of broad peak at around the 2θ value of 25 to 26° corresponded to highly
disordered parts and new peak at low angle at around the 2θ value of 5 to 6°
corresponded to successfully intercalation of PPy chain in the galleries of MMT clay. It
was observed that all the peak angles shifted and the full width at half maximum
(FWHM) values are difference with increasing in dopant concentrations and filler
percentages indicate the strong interaction between dopant and filler with the conjugated
polymer. The interchain separation showed good agreement with published data. |
