摘要: A series of polyaniline / montmorillonite clay (PANI-MMT) composites has been synthesised by solution polymerisation in the presence hydrochloric acid and a substoichiometric amount ammonium persulfate (APS). For preferred molar ratio monomer to oxidant 2:1, aniline was polymerised largely incorporated into MMT. The PANI-MMT were characterised compared Fourier-transform infrared (FTIR) spectroscopy, wide-angle powder X-ray diffraction scanning electron microscopy (SEM). effect loading with conducting polymer on nanocomposites' DC electrical conductivity studied, maximum (pressed compact) found be 4.73 x 10 -1 S.cm , comparable that pure same form. followed quite well temperature-dependence relationship □(T) = □ 0. exp[-T o /T) ½ ], characteristic one-dimensional variable-range hopping (1-D VRH).
