Abstract
This review explores the synthesis, characterization, and diverse applications of polyaniline (PANI)-based nanocomposites. PANI, known for its tunable electrical conductivity , eco-stability, and cost-effectiveness, has gained significant attention in advanced materials . This study focused on various preparation techniques, such as chemical oxidative polymerization, electrochemical polymerization , and vapor phase polymerization, highlighting their unique characteristics and impacts on nanocomposite performance. Critical applications of PANI nanocomposites are examined, including their roles in supercapacitors , sensors, solar cells, anticorrosion devices, water purification , and catalysis. Integrating PANI with metals, metal oxides , graphene, and carbon nanostructures enhances its functionality, making it a versatile candidate for innovative technological solutions. This review also addresses the challenges in commercializing PANI nanocomposites and proposes future research directions to overcome these obstacles.
