Abstract:

In this study nanofibres from poly(vinyl alcohol) (PVA) and thermoplastic polyurethane (TPU) polymers solutions were manufactured using the electrospinning method (NanospiderTM). During the electrospinning process, three different bottom rotating electrodes were used (spinning head):a plain cylindrical electrode and two different electrodes with tines. During the experiments, mats were manufactured from PVA nanofibres using all three types of electrodes. The structure of the electrospun PVA mats varied with a change of spin electrode. During the experiments, porous mats from TPU nanofibres were formed only using electrodes with tines (it was not possible to form TPU nanofibres using a plain cylindrical electrode). The shape of the bottom rotating electrodes does not have an influence on the diameter of electrospun PVA or TPU nanofibres.
