Controlling electrospun nanofiber morphology and mechanical properties using humidity

Liwei Huang, +3 more
- 15 Dec 2011 - 
TL;DR: In this article, the authors investigate how the humidity during electrospinning influences specific properties of the fiber mat, such as fiber diameter, surface morphology, and mechanical strength, and show that increasing humidity during spinning causes an increase in fiber diameter and a decrease in mechanical strength.
