Conducting polymers have attracted significant interest due to their unique combination of electrical conductivity and the properties of conventional polymers. Among them, polyaniline stands out as a promising material owing to its exceptional properties, facile synthesis, environmental stability, and versatility. This review provides a comprehensive overview of polyaniline, covering its synthesis methods, structure and properties, diverse applications, recent advances, and future perspectives. Chemical and electrochemical polymerization represent the primary synthesis routes, while novel approaches like template-assisted, microwave-assisted, and green synthesis methods have emerged. Polyaniline exhibits tunable electrical conductivity, reversible redox behavior, and characteristic optical properties arising from its conjugated structure. Its applications span conductive coatings, anticorrosion coatings, sensors, energy storage devices, and emerging areas like flexible electronics and bioelectronics. Recent research efforts have focused on functionalization strategies, nano-structuring, and advanced characterization techniques to enhance polyaniline’s performance and overcome limitations such as poor processability and environmental instability. Despite the progress made, challenges persist, necessitating further investigation into improving conductivity, stability, and solubility. Future directions include integrating polyaniline with emerging technologies, exploring sustainable synthesis methods, and developing advanced energy storage and biomedical applications. Overall, this review highlights the immense potential of polyaniline as a versatile conducting polymer and provides insights into ongoing research and future opportunities in this exciting field.
