 Full text | Abstract: Nowadays the electrospinning process is being widely investigated due to huge interest in nanotechnology science, but this process still has not been fully explained. So far there has been no general agreement amongst researchers about the influence of the main technological parameter – the influence of voltage applied on the diameter of manufactured nanofibres. In this study nanofibres were manufactured using the electrospinning method for a 12% concentration solution of poly(vinyl alchohol) (PVA) water solution. Two sets of experiments were performed in order to evaluate the influence of the voltage applied on the PVA nanofibre diameters. In the first case nanofibres were collected on a PES substratum, in the second – on a PP substratum. Next, the average nanofibre diameter was calculated from all derivatives of the nanofibres and only from the thinnest nanofibres. It was estimated, that the voltage applied does not have a noticeable influence on the diameter of the manufactured nanofibres. Only the structure consisting of nanofibre mats was influenced by the change in voltage. |
