This study describes the synthesis, characterization and properties of novel poly (4, 4-diaminodiphenyl sulphone) (PDDS) under effect of montmorillonite clay. The raw clay (called as Mag) was ion-exchanged with nickel nitrate and cobalt nitrate. The PDDS-Mag nanocomposites were prepared via in-situ emulsion polymerization process using ammonium persulfate as an oxidizing agent. Furthermore, the intercalation of PDDS into the clay layers were characterized and confirmed by chemical structure analysis using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV-visible spectra and scanning electron microscopy (SEM). The thermogravimetric analysis (TGA) thermograms showed an enhancement of the thermal stability of PDDS nanocomposites. The cyclic voltammetry indicate that the PDDS-clay nanocomposites have a good electrochemical response where achieve the anodic and cathodic peak at 540 mV and 320 mV, respectively. Moreover, these results show that the new synthesized conductive nanocomposites are environmentally friendly materials that can be utilized in many fields.
