Description 117-127
Nanocomposites of Poly (3,4-ethylenedioxythiophene) (PEDOT) and surfactant modified Maghnite clay have been
successfully synthesized by in situ polymerization of EDOT monomer in the interlayer space of the organoclay. The
synthesis has been assisted by ultrasonic method to improve the dispersion of PEDOT polymer between the Maghnite clay
sheets. The surfactant modified clay is synthesized via cation exchange method with Hydrogenure Tetrabutylammonuim
(TBAHS) and cetyltrimethylammonium (CTAB). Two types of organo-modified clays are obtained namely the Mag-TBA
and Mag-CTA according to the template used. Various physico-chemical techniques are used for nanocomposites
characterization such as XRD, FTIR, AFM, TGA/DTA, SEM and TEM. The results prove the formation of intercalated /
exfoliated upon increasing the content of organoclay in the nanocomposites , consequently, different morphologies and
structures in which the exfoliated and intercalated forms were obtained. Both nanocomposites display significant
enhancement in the thermal stabilities compared to the PEDOT polymer. However, a decrease in conductivity values is
observed for all samples compared to pure conducting polymer. This feature can be improved in view of desired application
in electrochemical devices.
