Abstract

Electrospinning is a simple and versatile technique for producing nanofibers from various materials including polymers, composites, carbons, ceramics, and metals. This presentation focuses on the development of different functional nanofibers for protecting human from chemical and biological threats. Nanofiber mats have small fiber diameters and large surface areas, and hence they can significantly increase the filtration efficiency without sacrificing the air permeability. In addition, by introducing functional materials into nanofibers, it is also possible to provide electrospun nanofibers with antibacterial and detoxifying properties. However, electrospun nanofiber mats are typically weak and do not have good mechanical properties. Here, we present a novel approach for fabricating durable and functional electrospun nanofibers that are suitable for practical chemical and biological application.
