A novel polyaniline–anionic spherical polyelectrolyte brushes (PANI/ASPB) nanocomposite was synthesised by means of chemical oxidative polymerisation. Different characterisation and analytical methods involving scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction and thermo-gravimetric analysis confirmed that anionic spherical polyelectrolyte brushes served both as a dopant and as a template. While polyaniline (PANI) nanocomposites have a ‘rod-like’ or fibrillar morphology, the PANI/ASPB nanocomposite displayed a sphere-like structure. The room temperature electrical conductivity of the PANI/ASPB nanocomposite was 26.3 S/cm, which is higher than that of PANI (7.1 S/cm). In addition, PANI/ASPB nanocomposites possessed enhanced thermal stability and good solubility properties.
