Description
The transition toward a sustainable, bio-based economy has sparked significant academic and industrial interest in engineering high-performance, functional nanomaterials from renewable resources. This review provides a comprehensive analysis of graphene quantum dot-nanocellulose (GQD–NC) composite materials, systematically evaluating their primary fabrication strategies, underlying interfacial architectures, and multi-sectoral applications. While nanocellulose variants, including highly rigid cellulose nanocrystals, flexible cellulose nanofibrils, and microbially derived bacterial nanocellulose, possess exceptional mechanical properties, high specific surface areas, and versatile surface tailorability, their pristine frameworks lack intrinsic optoelectronic and conductive functionalities. Conversely, zero-dimensional GQDs exhibit quantum-confinement-induced photoluminescence and enhanced boundary reactivity. However, they are constrained by limited processing versatility and tendencies toward self-quenching aggregation. Blending these distinct phases via liquid-phase solution mixing establishes an intimate molecular synergy governed by a cooperative network of non-covalent and covalent interactions. This interfacial synergy is fundamentally driven by the structural amphiphilicity of the repeating glucopyranose backbone, which dynamically balances equatorial hydrogen bonding with axial CH–π and basal π–π stacking interactions. Consequently, these composites exhibit optimized matrix crystallization and local energy stability, thereby enhancing macroscale tensile strength, toughness, and fluorescence response for advanced photonics, flexible energy-storage supercapacitors, and electroanalytical sensors. Furthermore, this review highlights critical processing paradoxes in automated 3D bioprinting bio-inks, detailing how maximizing static mechanical rigidity through advanced biomass functionalization—specifically, surface phosphorylation—can, counterintuitively, induce transient plug flow, shear-induced syneresis, and immediate nozzle occlusion under dynamic stress profiles. Finally, this review outlines key engineering bottlenecks, such as control of graphitic aggregation and compatibility issues with the hydrophobic polymer matrix, while offering perspectives on predictive molecular modeling and alternative non-wood extraction horizons to guide next-generation functional platforms.
