Innovative method for electrospinning of continuous TiO2 nanofiber yarns: Importance of auxiliary polymer and solvent selection

The different aspects of fabricating continuous TiO2 nanofiber yarns using oppositely charged metallic nozzles are studied. The importance of a proper auxiliary polymer, solvent and process required for continuous yarn formation are considered as effective process factors and are studied. Practical studies on solution concentration of the proposed polymer and solvent showed that it plays a significant role in the continuous electrospinning of nanofiber yarns and the diameter of nanofibers contained in the yarns.
