Abstract

Cellulose is the most abundant biomass material in the world. Magnetic nanoparticles can be used as reinforcing materials to give cellulose more functions due to their unique magnetism. According to the dispersion stability of nanocellulose, magnetic nanocellulose is divided into homogeneous preparation and heterogeneous preparation. In addition, the directional arrangement of nanocellulose by external magnetic field is also a way of cellulose functionalization. The current preparation of magnetic nanocellulose is mainly based on heterogeneous preparation. Magnetic nanofiber cellulose has great application potential in the field of biomedicine and sewage purification due to its special magnetic properties. It can also be applied to sensors, food packaging and other fields. In this paper, the preparation methods of magnetic nanocellulose and its physical magnetism are introduced. Then, the application of magnetic nanocellulose in different fields is reviewed. Finally, the current challenges of magnetic nanocellulose are summarized and the future development trend is prospected.

磁性纳米纤维素复合材料的制备及其应用研究进展

纤维素是世界上最丰富的生物质材料。磁性纳米颗粒由于其独特的磁性，可以作为增强材料赋予纤维素更多的功能。根据纳米纤维素的分散稳定性，将磁性纳米纤维素分为均相制备和非均相制备。此外，利用外加磁场对纳米纤维素进行定向排列也是纤维素功能化的一种方式。目前磁性纳米纤维素的制备主要是基于非均相制备。磁性纳米纤维纤维素由于其特殊的磁性能，在生物医学和污水净化领域具有巨大的应用潜力。也可应用于传感器、食品包装等领域。本文介绍了磁性纳米纤维素的制备方法及其物理磁性。然后，综述了磁性纳米纤维素在不同领域的应用。最后，总结了磁性纳米纤维素目前面临的挑战，并对其未来发展趋势进行了展望。

期刊介绍： Carbohydrate Polymers stands as a prominent journal in the glycoscience field, dedicated to exploring and harnessing the potential of polysaccharides with applications spanning bioenergy, bioplastics, biomaterials, biorefining, chemistry, drug delivery, food, health, nanotechnology, packaging, paper, pharmaceuticals, medicine, oil recovery, textiles, tissue engineering, wood, and various aspects of glycoscience. The journal emphasizes the central role of well-characterized carbohydrate polymers, highlighting their significance as the primary focus rather than a peripheral topic. Each paper must prominently feature at least one named carbohydrate polymer, evident in both citation and title, with a commitment to innovative research that advances scientific knowledge.
