功能性纤维素微球的制备及其应用研究进展

Progress in preparation and application of functional cellulose microspheres

摘要:

近年来，随着石油基聚合物带来的危害日益显现以及“碳达峰”和“碳中和”理念的提出，纤维素微球作为新型生物基材料，因其具有化学性质稳定、比表面积大、生物相容性好、应用领域广及成本低等优点，成为了新的研究热点，并有望被广泛应用于污染物吸附、生物技术、药物工程、医学工程等领域。然而，纤维素微球目前还存在着难以精确控制和干燥条件苛刻等缺点。基于近年来纤维素微球的研究，介绍了纤维素微球的制备机理，阐述了改性方法对纤维素微球功能化的影响，总结了纤维素微球在不同领域的应用情况，并对其未来的发展趋势进行了评述。

Abstract:

In recent years, with the increasing harm brought by petroleum based polymers and the proposal of the concepts of "carbon peak" and "carbon neutralization", cellulose microspheres, as a new bio based material, have become a new research hotspot because of their stable chemical properties, large specific surface area, good biocompatibility, wide application fields and low cost, and are expected to be widely used in pollutant adsorption Biotechnology, pharmaceutical engineering, medical engineering and other fields. However, cellulose microspheres also have some disadvantages such as difficult to control accurately and harsh drying conditions. Based on the research of cellulose microspheres in recent years, the preparation mechanism of cellulose microspheres was introduced, the influence of modification methods on the different functions of cellulose microspheres was explored, the common applications of cellulose microspheres were summarized, and the development trend of cellulose microspheres in the future was reviewed.
