NANOFIBROUS MATERIALS AND THEIR APPLICATIONS

TLDR

Nanofibrous materials are now more readily available due to advances in electrospinning and related techniques, enabling adjustable composition and tunable physical parameters that produce high surface‑to‑volume ratios and interconnected pores for diverse biomedical and industrial applications. This review selectively describes the fabrication of nanofibrous membranes and their applications, with particular emphasis on anti‑adhesion in surgery and ultrafiltration in water treatment. The authors discuss electrospinning fabrication methods and illustrate how the resulting nanofibrous membranes are applied in anti‑adhesion surgical contexts and ultrafiltration water treatment.

Abstract

▪ Abstract Nanostructured fibrous materials have been made more readily available in large part owing to recent advances in electrospinning and related technologies, including the use of electrostatic or gas-blowing forces as well as a combination of both forces. The nonwoven structure has unique features, including interconnected pores and a very large surface-to-volume ratio, which enable such nanofibrous scaffolds to have many biomedical and industrial applications. The chemical composition of electrospun membranes can be adjusted through the use of different polymers, polymer blends, or nanocomposites made of organic or inorganic materials. In addition to the control of material composition, the processing flexibility in maneuvering physical parameters and structures, such as fiber diameter, mesh size, porosity, texture, and pattern formation, offers the capability to design electrospun scaffolds that can meet the demands of numerous practical applications. This review provides a selective description of the fabrication of nanofibrous membranes and applications with specific examples in anti-adhesion in surgery and ultrafiltration in water treatment.
