A strategy to prepare flower-like polyaniline (PANI) microspheres was successfully developed. The structure of the flower-like PANI microspheres was characterised by means of scanning electron microscopy, UV–vis spectra and Fourier transform infrared spectroscopy. These results showed the formation of flower-like PANI microspheres with average diameter of about 8 µm. The effect of the reaction time on morphology and electrical conductivity of the polyaniline was further investigated in detail. It showed that the morphology and electrical conductivity of PANI strongly depended on the polymerisation time. Also, the flower-like PANI has higher electrical conductivity compared with that of PANI with others morphology. The result indicates that the flower-like PANI is better to apply on electromagnetic interference shielding materials.
