Abstract:
Conducting polymer nanocomposites have emerged as multifunctional materials that combine the electrical activity of conjugated polymers with the mechanical, thermal, optical, magnetic, catalytic, or electrochemical characteristics of nanoscale fillers. Polyaniline (PANI), polypyrrole (PPy), polythiophene and poly(3,4-ethylenedioxythiophene) (PEDOT) are among the most extensively investigated conducting polymers, while graphene, graphene oxide, reduced graphene oxide, carbon nanotubes (CNTs), metallic nanoparticles, metal oxides, and two-dimensional materials such as MXenes are widely used as nanofillers. However, the macroscopic performance of these composites is not determined only by the intrinsic properties of their individual components. The interface between the conducting polymer and nanofiller plays a decisive role in dispersion, adhesion, charge transfer, interfacial polarization, mechanical stress transfer, electrochemical activity, and long-term stability. This article reviews the principles of interface engineering in conducting polymer nanocomposites, important interaction mechanisms, fabrication strategies, characterization approaches, effects on electrical, mechanical, thermal and electrochemical properties, and applications in sensors, supercapacitors, batteries, electromagnetic interference shielding, flexible electronics, bioelectronics and energy-related technologies. Particular attention is given to the relationship between interfacial structure and functional performance and to future directions involving molecular-level interface control, multifunctional interfaces, scalable processing and sustainable nanocomposite design.
