In this study nanofibres from poly(vinyl alcohol) (PVA) polymers solutions were collected on different types of support material by the electrospinning method (NanospiderTM). During the electrospinning process, the following three different grounded electrodes were used: I - a ylindrical electrode II - a wire grounded electrode, III - a wire grounded electrode, whose distance to the support material was 40 mm. The aim of this research was to investigate the influence of the type of grounded electrode on electrospun PVA nanofibres collected on different support materials and their structure. During the experiments, it was noted that the type of grounded electrode has an influence on a electrospun mat with a PVA nanofibre structure. The diameter of electrospun PVA nanofibres does not depend significantly on the type of grounded electrode and nature of the support material, although it is possible to notice the tendency that it is possible to form a bigger amount of thinner nanofibres using type I grounded electrode.

Abstract:

 

In this study nanofibres from poly(vinyl alcohol) (PVA) polymers solutions were collected on different types of support material by the electrospinning method (NanospiderTM). During the electrospinning process, the following three different grounded electrodes were used: I - a ylindrical electrode II - a wire grounded electrode, III - a wire grounded electrode, whose distance to the support material was 40 mm. The aim of this research was to investigate the influence of the type of grounded electrode on electrospun PVA nanofibres collected on different support materials and their structure. During the experiments, it was noted that the type of grounded electrode has an influence on a electrospun mat with a PVA nanofibre structure. The diameter of electrospun PVA nanofibres does not depend significantly on the type of grounded electrode and nature of the support material, although it is possible to notice the tendency that it is possible to form a bigger amount of thinner nanofibres using type I grounded electrode.
