Electroactive polymer composites and hybrid materials have attracted a great deal of attention due to their potential application in catalysis, sensing, energy storage (solar cells, lithium-ion batteries, and supercapacitors), and electronic devices.

The properties of polymer composites and hybrid materials strongly depend on their composition and synthesis processes. The combination of unique properties resulting from the arrangement and interactions between different constituents offers immense possibilities for advanced materials technologies.

The aim of this Special Issue is to collate original research and review articles with a focus on synthesis, characterization to accomplish a more detailed understanding of the interplay between synthesis, structure, characterization, processing, application, and performance of these advanced materials, with focusing on electrochemical applications.

Potential topics include but are not limited to the following:

• Synthesis and characterization of electroactive polymers, composites, and hybrid materials
• Functional polymer composites and hybrid material modified electrodes
• Electrochemical characterization and applications of polymer composites and hybrid materials
• Nanomaterials applications for enhancing electroactive activity
• Applications of electroactive-based polymers and nanocomposites
