The Porosity of Nanofiber Layers

Nanofiber layers have recently received lots of attention. These layers can be produced in various methods, but the most common is electrospinning. Therefore, this chapter focuses on the nanofiber layers from electrospinning. The porosity of nanofiber layers is a critical property. Several methods can be used to measure this value. Also, there are numerous methods for controlling and changing it. The porosity is an essential property for the application of nanofiber layers. Each application requires a unique set of porosities. As a result, measuring and controlling the porosity with high precision is critical for applying nanofiber layers. This chapter concentrated on porosity measurement and control methods and the importance of porosity in applications
