Conductive polymer nanocomposites are hybrid materials that combine organic and inorganic particles. The review focuses on polymer nanocomposites, an important area of interest in nanotechnology and conductive materials. Conductive polymers exhibit special conductivity and charge-transport characteristics. The introduction of nanomaterials into these polymers improves performance and application properties. The aim of this project is to complete the evaluation of research and studies carried out in this field. Investigate several factors that improve the conductivity of polymers, involving the type of nanomaterial used, its structural properties, its arrangement in the polymer matrix, and its influence on electrical conductivity, material flexibility, chemical resistance, and thermal stability. In addition, it explores the methods and techniques used in the manufacture of polymer nano conducting. In addition, the practical applications of polymer nanocomposites in electronic devices, energy storage and conversion, sensors, actuators, and biomedical applications are assessed critically. It examines the potential advantages and challenges of these applications and emphasizes the possibility of the production and application polymer nanocomposites in different industries.
