Abstract The increasing request for lightweight, environmentally sustainable materials with versatile functionality and strong mechanical properties is driving renewed interest in nanocellulose electrical applications. Nanocellulose, a biologically derived polymeric nanomaterial, has seen significant growth the global market due to advancements nanotechnology need materials. This accelerated research into development of cellulose-based nanomaterials. However, on its own does not inherently possess ability function as conductive material. To address this limitation, researchers have explored various modifications, such combining or applying specific chemical treatments. These approaches been shown enhance conductivity nanocellulose, making it suitable use electrically composites. Over past few decades, composites extensively studied their applications energy, electronics, biomedicine, health, environmental sectors. Nanocellulose possesses unique combination exceptional properties, including biodegradability, renewability, distinctive fibrous structure, proving that best choice these uses. superior nanocellulose-based composites, coupled flexibility, ease production, biocompatibility, make them highly desirable advanced technological Significant achieved by fabricating types exploring potential nanogenerators, humidity sensors, gas supercapacitors. modify surface robust offer numerous opportunities creating hybrid within domain.
