Polyaniline (PANI) has recently received sustained attention due to its outstanding electrical properties, good chemical and environmental stability, simple preparation process, and extensive application in numerous fields such as chemical sensor, corrosion devices, photovoltaic cell, gas separation membranes, etc. However, the main drawback of PANI is poor solubility caused by the rigid backbone. Interestingly, the chemically modified PANI not only shows improved processability, but exhibits better conductive and anticorrosion properties than pure PANI. This review mainly highlights the developments in chemical modifications of PANI with enhanced properties over the last decades, which would be helpful for guiding the rational design of PANI in structure and property in order to further cater the practical demands.
