Özet

This work focuses on the preparation, characterization and electrical conductive properties of intercalated polyaniline/Na-montmorillonite nanocomposites. These materials consisting of polyaniline and Na-montmorillonite were prepared by oxidative polymerization with benzoyl peroxide as oxidizing agent. The synthesized nanocomposites were investigated by a series of characterization techniques; including Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, and thermal analysis. X-ray diffraction and scanning electron microscopy images showed that the polyaniline was inserted into the clay layers. The modest increase in layer spacing was as much as 0.53 nm. The thermogravimetric analysis and differential thermal analysis demonstrated the improved thermal stability of the intercalated nanocomposites relative to the pure polyaniline due to the incorporated Na-montmorillonite. The room temperature electrical conductivity of nanocomposites varied from 1.0 x 10(-7) to 5.8 x 10(-5) Scm(-1).
