Chitosan is a natural fiber, chemically cellulose-like biopolymer, which is processed from chitin. Its use as a natural polymer is getting more attention because it is non-toxic, renewable, and biocompatible. However, its poor mechanical and thermal strength, particle size, and surface area restrict its industrial use. Consequently, to improve these properties, cellulose and/or inorganic nanoparticles have been used. This review discusses the recent progress of chitosan and cellulose composite materials, their preparation, and their applications in different industrial sectors. It also discusses the modification of chitosan and cellulose composite materials to allow their use on a large scale. Finally, the recent development of chitosan composite materials for drug delivery, food packaging, protective coatings, and wastewater treatment are discussed. The challenges and perspectives for future research are also considered. This review suggests that chitosan and cellulose nano-composite are promising, low-cost products for environmental remediation involving a simple production process.
壳聚糖是一种天然纤维,化学上类似于纤维素的生物聚合物,由几丁质加工而成。由于其无毒、可再生和生物相容性,作为天然聚合物的用途越来越受到关注。然而,其较差的机械和热强度、颗粒大小和表面积限制了其工业用途。因此,为了改善这些性能,已经使用了纤维素和/或无机纳米粒子。本文综述了壳聚糖和纤维素复合材料的最新进展,包括其制备方法及其在不同工业领域的应用。还讨论了壳聚糖和纤维素复合材料的改性,以允许其大规模使用。最后,讨论了壳聚糖复合材料在药物输送、食品包装、防护涂层和废水处理方面的最新发展。还考虑了未来研究的挑战和前景。本文综述表明,壳聚糖和纤维素纳米复合材料是一种有前途的、低成本的产品,可用于涉及简单生产过程的环境修复。
