Polymer and Ceramic-Based Hollow Nanofibers via Electrospinning

Polymer and ceramic-based hollow nanofibers (NFs) are gaining a lot of attention in the scientific community for a variety of applications in the areas of sensing, environment, energy, and health. They possess various properties such as large surface area, high porosity, and sensitivity. The ceramic and polymer-based hollow NFs exhibit higher space charge modulation depth, larger electronic transport properties, and shorter ion diffusion length. A lot of work has been done on using ceramic-based hollow NFs while in the case of polymer-based hollow NFs, no significant research has been conducted to date. This chapter discusses the different types of hollow NFs produced by electrospinning and their application in various fields. The area of NF fabrication is still advancing and a lot more research can be done efficiently to explore more of their applications in various sectors.
