Carbon‑based and polymeric functional materials are playing an increasingly central role in next‑generation electrochemical energy storage and bioelectronic devices. Graphene and related nanocarbons, MXenes, conductive polymers, supramolecular networks, and their hybrids offer unique combinations of electronic and ionic conductivity, mechanical tunability, and interfacial adaptability. These characteristics enable high‑performance electrochemical capacitors for line filtering, advanced secondary batteries, and robust bioelectronic interfaces for sensing, stimulation, and actuation.
Recent progress in material synthesis, structural design, and interfacial engineering has opened new avenues to precisely tailor charge‑transport pathways, decouple ionic and electronic conduction, and integrate soft materials with hard device architectures. At the same time, understanding how molecular structure, nano‑/micro‑architecture, and processing routes govern device‑level metrics—such as impedance, frequency response, cycling stability, electrochemical window, and biocompatibility—remains a key challenge.
This Research Topic focuses on the design, synthesis, and application of carbon‑based and polymeric materials for advanced electrochemical and bioelectronic devices. Particular emphasis is placed on:
• Novel graphene‑, MXene‑ and other carbon‑based composites for electrochemical capacitors, line‑filtering devices, and secondary batteries.
• Interface and electrolyte engineering for stable metal anodes, optimized solid–electrolyte interphases, and improved ion transport.
• Conducting polymer and supramolecular polymer systems for high‑fidelity bioelectrodes, multimodal biointerfaces, and soft actuators.
• Strategies to decouple and control ionic and electronic charge transport in hybrid materials and devices.
• Structure–property–performance relationships linking molecular design and microstructure to mechanical robustness, flexibility, healing capability, and long‑term stability in electrochemical and bioelectronic environments.
We welcome Original Research, Reviews, and Perspectives that provide fundamental insights or application‑oriented advances in material design, device architecture, and interfacial phenomena for electrochemical energy storage, line filtering, and bioelectronic systems.
