The chemical modification of polyaniline with enhanced properties: A review

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...
