Mechanical Properties of Electrospun Fibers—A Critical Review

Advanced Engineering Materials, Journal Year: 2021, Volume and Issue: 23(9)

Published: May 18, 2021

The mechanical properties of electrospun fibers play an important role in determining their applications. Most the reported literature measures mats, scaffolds, or films instead single fibers; however, a basic understanding relationship between fiber and that mat is critical to obtain precise information for choosing application. This Review aims evaluate variables influence those properties. An overview on recent inputs development given, illustrating attempts tailor and/or mats. necessity flexible reliable testing methods establish standards obtaining consistent data both mats also highlighted.
