Cellulose, the most abundant natural polymer, is emerging as a versatile biomaterial platform for sustainable advanced electronics beyond its conventional role as a passive substrate. Its hierarchical fibrillar architecture and hydroxyl-rich chemistry enable unique combinations of mechanical compliance, interfacial reactivity, ionic transport, and optical transparency. This perspective highlights cellulose as a multifunctional system spanning structural and interfacial integration, ionic-electrochemical behavior, and optoelectronic interfaces, which together underpin its growing relevance in flexible, energy, and transparent electronic technologies. However, intrinsic coupling between hydrat... More >

The growing demand for sustainable materials in green flexible electronics calls for alternatives to petroleum-derived polymers, which are non-biodegradable, resource-intensive, and environmentally harmful. This study presents the fabrication of bio-composite films using water hyacinth derived cellulose nanofibrils (CNF), blended with polyethylene oxide (PEO) and reinforced by functional nanofillers such as barium titanate (BTO), silver nanowires (SNP), and carbon nanotubes (CNT). The nanocomposite films (NCF) were produced by solution casting and systematically characterized for morphological, dielectric, mechanical, thermal, and chemical properties. Scanning electron microscopy analysis re... More >
