Abstract
En 中文
Liquid metals (LM) with exceptional flexibility, deformability, conductivity, biocompatibility, conductivity and healable capability have emerged as a promising class of materials for developing advanced functional materials. However, the high surface tension of LM leads to aggregation and leakage issues. Lignocellulose (cellulose, hemicellulose and lignin) possessing numerous active groups are suitable for encapsulating and dispersing the LM droplets. Although research on lignocellulose-LM composites has advanced, systematic investigations into the lignocellulose-LM interfacial interactions, spanning from molecular-level bonding mechanisms to macroscale materials processing methods, remain limited. This review addresses these gaps by examining LM preprocessing techniques, interfacial interactions with lignocellulose and fabrication strategies for forming stable composites. Special emphasis is placed on the dispersing and stabilizing effects of lignocellulose on LM, offering insights for designing high-performance materials. In addition, the latest progress in integrating LM with lignocellulose for functional material fabrication is summarized. Key challenges (including interfacial engineering, long-term biocompatibility and environmental risks) are critically assessed. The review also proposes multidimensional design principles and sustainability metrics to support the transition of lignocellulose-LM composites toward intelligent manufacturing systems. In conclusion, this review highlights the importance of understanding lignocellulose-LM composites and offers essential guidance for future research in this emerging field.
