     this article provides a brief overview of recent work by the authors’ group as well as related researches reported by others on controlling the morphology and exploring the formation mechanism of typical micro-/nanostructures of polyaniline (pani) and aniline oligomers through template-free aniline chemical oxidation process. the contents are organised as follows: (i) tuning the morphology of aniline polymerisation products by employing ultrasonic irradiation, mass transfer, and ph profiles; (ii) exploring the formation mechanism of micro-/nanostructures during aniline chemical oxidation through examining the precipitation behaviours of aniline oligomers and polymers in a post-synthetic system; (iii) tailoring pani micro-/nanostuctures into pre-designed morphology by introducing certain heterogeneous nucleation centres; (iv) application potential of pani nanofibres in the areas of transparent conductive film, electromagnetic interference-shielding coating and graphene-based electrode materials. this short review concludes with our perspectives on the challenges faced in gaining the exact formation mechanism of pani micro-/nanostructures and the future research possibility for morphologically precisely controlled pani micro-/nanostructures.
