Abstract

Ongoing global health and environmental crises, such as the outbreak of infectious diseases, contaminated drinking water sources, or air pollution, have increased the demand for exploring functional nonwovens for filtering applications. The current paper presents a literature review on filters made of biodegradable cellulose via electrospinning with antiviral capabilities. Initially, a short overview of the filtration process in relation to the aim application (air or water filtration) is provided. Furthermore, the electrospinning technique, including its setup, parameter adjustments, and potential geometric fiber outcomes is presented considering the targeted applications. The suitability of natural biodegradable cellulose (and its derivatives) for producing nonwoven electrospun antiviral filters is discussed. Finally, a comprehensive summary of the recent publications (2020–2024) reporting on electrospun cellulose-based filters with antiviral properties is provided, followed by a brief discussion on the current challenges and future perspectives in this field.

具有抗病毒性能的电纺丝纤维素过滤器：近5年的发展综述

持续的全球健康和环境危机，如传染病的爆发、饮用水水源的污染或空气污染，增加了对探索过滤应用的功能性非织造布的需求。本文综述了生物可降解纤维素静电纺丝制备的具有抗病毒功能的过滤器的研究进展。首先，提供了与目标应用（空气或水过滤）相关的过滤过程的简短概述。此外，还介绍了静电纺丝技术，包括其设置、参数调整和潜在的几何纤维结果。讨论了天然可生物降解纤维素（及其衍生物）用于生产无纺布静电纺抗病毒过滤器的适用性。最后，全面总结了最近（2020-2024）关于具有抗病毒特性的基于电纺纤维素的过滤器的报道，然后简要讨论了该领域当前的挑战和未来的前景。
