Polypyrrole (PPy) has unique features such as easy synthesis, environmental stability, and high electrical conductivity (approximately 105 S/cm and even >380 S/cm) for bulk and thin‐film materials. Thus, PPy is applied in numerous well‐established applications, such as in sensors, supercapacitors, and resonators. These applications take advantage of the unique properties achieved through the structure and properties of PPy. This article comprehensively elaborates the methods used to synthesize conductive PPy, along with the important factors affecting its conductivity. Emphasis is given to versatile and basic approaches that enable control of the microstructural features that eventually determine PPy conductivity. Despite the intensive research in this area, no previous study has presented all possible relevant information about PPy fabrication and the important factors influencing its electrical conductivity.
