Abstract

This study dealt with providing an efficient method of preparing NiS-montmorillonite (NiS-MMT) nanocomposite with an electric conducting property. The first step in the process involved an ultrasound-assisted cation-exchange reaction between pure montmorillonite and nickel (II) solution. The second step was the solid phase reaction between the Ni-modified montmorillonite and sodium sulfide (Na₂S). Thermogravimetric analysis showed that the weight loss at 428^oC – 850^oC implied greater thermal stability of the nanocomposite. This is due to a more ordered and dense microstructure of NiS-MMT as revealed by the scanning electron micrographs. An increased conductivity of 2.03x10^-4 S·m^-1 was measured from the prepared NiS-MMT.
