摘　　要：细菌纤维素纳米纤维是一种生物相容性和力学性能优异的天然纳米材料,具有纯度高、聚合度高、结晶度高、持水性好、长径比大等优点,可通过多种方法与高分子复合,其中的关键问题是如何进行改性以提高纳米纤维与高分子界面相容性及纳米纤维在高分子中分散的均匀性,进而提高复合材料的性能、拓宽应用领域。本文综述了细菌纤维素纳米纤维改性及其复合材料的最新研究进展,主要包括改性机理、制备方法、性能特点和潜在应用。Bacterial cellulose nano-fiber is a kind of natural nano material with excellent biocompatibility and mechanical properties. It also has the advantages of high purity, high degree of polymerization, high crystallinity, good water holding capacity and large aspect ratio. A variety of methods can be used to combine bacterial cellulose nano-fiber and polymers. The key challenge is how to modify it to improve the interfacial compatibility of nano-fiber and polymer and the uniformity of nano-fiber in polymer, thereby improving the properties of composites and expanding its applications. In this paper, the latest research progress on the modification of bacterial cellulose nano-fiber and their composites are briefly reviewed, including modification mechanisms, preparation methods, performance characteristics and potential applications.
