2D Nanofillers in Natural Fiber Composites: Bridging Sustainability and High‐Performance Materials

ABSTRACT Natural fiber composites (NFCs) have been materialized as eco‐friendly, viable alternatives to synthetic fiber systems on account of its lightweight nature, biodegradability, and sustainability. Nevertheless, their restricted thermal resilience, mechanical properties, and moisture affinity confine their advanced applications. The emergence of 2D nanofillers offers a transformative solution to these challenges, enabling the integration of nanofillers with natural fibers to enhance their properties. The outstanding mechanical characteristics, high aspect ratios, and versatility of these nanostructures prove their potential to improve the inadequate properties of NFCs remarkably. This review elucidates the 2D nanofiller incorporation into natural fiber composites, concentrating on their synthesis, properties, applications, and compatibility with different natural fibers. Furthermore, the role of 2D nanostructures in enhancing the thermal, mechanical, and electrical properties of natural fibers and their impact on different applications is also extensively discussed. Overall, this review targets to bridge the research gap between sustainability and advanced materials science, laying the foundation for the innovative future of natural fiber composites.
