Efficient air filtration through advanced electrospinning techniques in nanofibrous Materials: A review

Air pollution has emerged as one of the key factors in the expected rise in cancer incidence. Air pollution has caused an enormous threat to human health. Air filtration is an effective technology to improve air quality, and the promotion of air filtration materials (AFMs) has been a prominent research frontier. This paper explores the application of electrospinning technology in air filtration, focusing on how the design and structure of electrospun nanofibers affect their performance. Based on the existing literature, we comprehensively and systematically analyze the influence of factors such as structure, parameters, and electrostatic effects on the performance of air filtration, including two-dimensional membranes composed of smooth or highly structured fibers. We also extend the three-dimensional structure and recent advances in the study of friction electricity on air filtration. In addition, it also involves industrialized electrospinning applied to air filtration, which provides a future direction for the exploration of new structures and methods of air filtration materials as well as the large-scale production of electrospinning.
