Polymeric ionic liquid poly(imidazolium chloride-4,6-dinitrobenzene-1,3-diyl) was synthesised by N-arylation of imidazole using 1,3-dichloro-4,6-dinitrobenzene and characterised by H-1 and C-13 nuclear magnetic resonance, Fourier transform infrared, ultraviolet-visible, gel permeation chromatography, scanning electron microscopy, energy dispersive X-ray spectroscopy and X-ray diffraction. The results showed that the desired ionic liquid polymer was achieved successfully with amorphous structure and spherulitic morphology with particle diameter of similar to 200 nm. Its number average molecular weight M-n and weight average molecular weight M-w were 1517 and 2543 respectively. Furthermore, the thermogravimetric analysis, mass spectrometry and ionic conductivity analysis showed that the polymer possessed good thermal stability below 500 degrees C and a high ionic conductivity of 28.88 mu S cm(-1) at room temperature compared with well known polyaniline.
