The effects of relative humidity and salt concentration on the diameter of hydrophilic polymeric nanofibers obtained by electrospinning: synergistic effect study by Central Composite Design (CCD). Supplementary Material

Results of the 39 experiments of CCD
The next micrograph show the experiments of PVA, PVP and PEO fibers obtained by electrospinning technique with and without HAuCl4•3H2O
Table 1 and 2 shows. The summary of mean diameter of the fibers obtained by 3 micrograph in three different pints and its respective standard deviations at different Relative Humidity (%)/Temperature (°C) ratio. No fibers were obtained for PVP as show in Figure 3.
