     this study investigates the effect of the ionic liquid 1-butyl-3-methyl imidazolium chloride ([bmim]cl) on the morphological, structural, and electronic properties of polyaniline (pani) products synthesised by the falling-ph method. products were characterised by sem, ft-ir, uvvis, n2-physisorption, and conductivity measurements. the [bmim]cl addition strongly influenced the pani morphology, specific surface area, porosity, and conductivity. depending on the [bmim]cl: ani ratio and the synthesis ph, a wide range of pani nanostructures could be prepared, with rod-like, and fibre-like elongated structures being the dominant morphology under most experimental conditions. samples prepared in the presence of [bmim]cl exhibit specific areas of ca 22–35 m2 g−1. the conductivity of the final products depends on the [bmim]cl: ani ratio. temperature dependence of conductivity in the temperature range from 77 k to 300 k was also studied.
