| Abstract Scope |
The rising demand for biodegradable and high-performance electronic materials has driven the exploration of bio-based ferroelectric systems. This study introduces a novel class of nanostructured bacterial cellulose (BC) films functionalized with silver (Ag) and zinc oxide (ZnO) nanoparticles, derived from Nata de coco waste, to enhance ferroelectric behavior. The integration of conductive AgNPs and semiconductive ZnONPs significantly increased remnant polarization (Pr up to 0.1 µC/cm2) and dielectric constant (ε′ up to 8.23), compared to pristine BC. These enhancements are attributed to the induced dipole alignment and electrostatic interactions between nanoparticles and the BC matrix. Furthermore, electrical poling at 360 kV/cm markedly improved ferroelectric performance across all films. The resulting nanocomposite films exhibit strong potential for flexible sensors, energy harvesting devices, and environmentally friendly electronics. This work not only demonstrates an effective route to sustainable functional materials but also underscores the value of waste-derived BC in advanced applications. |
