Nanofibres have gained attention for their highly porous structure, narrow pore size, and high specific surface area. One of the most efficient techniques for producing nanofibres is electrospinning. These fibres are used in various fields, including water filtration. Although they possess the ability to filter various components, the fibres generally have low mechanical strength, which can mitigate their performance over time. To address this, studies have focused on enhancing nanofibre membrane strength for water filtration. Previous analyses show that the mechanical properties of nanofibre mats can be improved through solvent vapour treatment, thermal treatment, and chemical crosslinking. These treatments promote interfibre bonding, leading to the improvement of mechanical strength. However, excessive treatment alters nanofibre behaviour. Excessive heat exposure reduces interfibre bonding, while too much solvent vapour decreases pore size and mechanical strength. Thus, a comprehensive understanding of these post-treatments is crucial. This review examines post-treatments aiming to increase the mechanical strength of nanofibre mats, discussing their advantages and disadvantages. Understanding these treatments is essential for optimising nanofibre membrane performance in water filtration and other applications.
纳米纤维因其高度多孔的结构、狭窄的孔径和高比表面积而受到关注。生产纳米纤维最有效的技术之一是静电纺丝。这些纤维被用于包括水过滤在内的各个领域。尽管它们有能力过滤各种成分，但这些纤维通常机械强度较低，这会随着时间的推移而降低其性能。为了解决这个问题，研究集中在提高用于水过滤的纳米纤维膜的强度上。先前的分析表明，纳米纤维毡的机械性能可以通过溶剂蒸汽处理、热处理和化学交联来改善。这些处理促进了纤维间的结合，从而提高了机械强度。然而，过度处理会改变纳米纤维的性能。过度受热会减少纤维间的结合，而过多的溶剂蒸汽会减小孔径并降低机械强度。因此，全面了解这些后处理至关重要。本综述考察了旨在提高纳米纤维毡机械强度的后处理方法，讨论了它们的优缺点。了解这些处理方法对于优化纳米纤维膜在水过滤和其他应用中的性能至关重要。
