Electrospinning and Electrospraying Techniques for Nanocomposite Non-Woven Fabric Production

摘要

Electrospinning and electrospraying processes were tested as tools for the production of non-woven nanocomposite fabric from a polymer material with nanoparticles deposited on a fibre surface. The suitability of two main electrospraying/electrospinning systems was investigated: the consecutive electrospraying of nanoparticle colloidal suspension after electrospinning polymer solution, and the simultaneous electrospinning of polymer solution and electrospraying of nanoparticle colloidal suspension from two separate capillary nozzles. In our experiments the fibres were electrospun from PVC, PSU and PA6 polymers in suitable solvents. Electrosprayed fibres were the colloidal suspensions of TiO_2, ZrO_2, MgO, or Al_2O_3 nanoparticles of 20 to 100 nm in size.
