Biomass‐Derived Materials for Organic Electronics

ABSTRACT

The growth of flexible, wearable, and disposable organic electronics increases the need for materials and processing strategies that reduce fossil‐resource dependence and improve end‐of‐life management. Biomass‐derived materials provide a promising route because their diversity and hierarchical structures enable functions ranging from mechanical support and dielectric behavior to interfacial modification, conductivity, sensing, and sustainable processing. This review classifies biomass‐derived materials for organic electronics into four categories: naturally occurring biomass polymers and composites, biomass‐derived functional polymers, biomass‐derived carbon materials, and renewable solvents and processing aids. Applications in thin‐film transistors, organic solar cells, memory devices, wearable sensors, and flexible electronics are examined, emphasizing relationships among material origin, transformation route, device function, and electronic performance. Biomass‐enabled systems are benchmarked against conventional materials to identify advantages and remaining gaps. The review distinguishes renewable origin from biodegradability, recyclability, and sustainability, and evaluates biomass‐enabled electronics using a five‐stage framework encompassing feedstock sourcing, material conversion, device fabrication, operation, and end‐of‐life. Key challenges include feedstock variability, processing intensity, interface compatibility, moisture sensitivity, inconsistent benchmarking, and end‐of‐life testing. Overall, biomass integration is most compelling when renewable sourcing is combined with competitive device performance, reduced processing burden, extended service life, or credible recovery and degradation pathways.
