纳米纤维，主要是由静电纺丝制备的，在许多新兴的环境应用中表现出巨大的潜力。它们可以被认为是最安全的纳米材料之一，因为它们的长度极长（可达数百公里），并且能够嵌入其他介质中。它们的高表面积与体积比、大孔隙率（高达80%以上）和可调节的功能性在颗粒分离和液体过滤方面也比传统的非织造膜和聚合物膜有效得多。用于纳米纤维的大规模生产的多射流电纺和电吹等技术进步使得使用纳米纤维支架作为用于气体和液体过滤的分离介质中的独特和突破性组分变得切实可行。在这篇综述中，使用功能性纳米纤维的几个代表性的环境应用的机遇和挑战进行了审查。
Nanofibers, mainly fabricated by electrospinning, have exhibited great potential for many emerging environmental applications. They can be considered as one of the safest nanomaterials due to their extremely long length (can be up to hundreds of kilometers) and their ability to be embedded within other media. Their high surface-to-volume ratio, large porosity (up to over 80%) and adjustable functionality are also much more effective than conventional non-woven and polymeric membranes in particulate separation and liquid filtration. Technology advances such as multiple-jet electrospinning and electroblowing for mass production of nanofibers have made it practical to use nanofibrous scaffolds as a unique and breakthrough component in separation media for both gas and liquid filtration. In this review, the opportunities and challenges of using functional nanofibers for several representative environmental applications are reviewed.
