Figure 2: Nanofibres and fabrication parameters. (a) An SEM picture of EVOH nanofibres produced with a solution in a stabilized temperature; (b) an SEM picture of EVOH nanofibres with a solution in decreasing temperature; (c) effect of the voltage on fibre diameters when the solution density is 7.5% (wt) and needle tip-to-collector distance is 30 cm; (d) effect of the density on fibre diameters when the voltage is 20 kV and the tip-to-collector distance is 30 cm; (e) effect of the distance on fibre diameters when the solution density is 7.5% (wt) and the voltage is 20 kV; (f) an example of SEM measurement of fibre diameters.
