EFFECT OF SOLUTION PROPERTIES ON FIBER DIAMETERS OF POLYVINYL ALCOHOL NANOFIBROUS MATS
In this study, PVA (polyvinyl alcohol) solutions with different concentrations (8, 10, 12, 14, 16 and 18 wt %) were prepared and nanofibers were produced with changing system parameters via electrospinning. Image analysis was performed after FESEM analysis using Image J programme. Prior to electros...

| description | In this study, PVA (polyvinyl alcohol) solutions with different concentrations (8, 10, 12, 14, 16 and 18 wt %) were prepared and nanofibers were produced with changing system parameters via electrospinning. Image analysis was performed after FESEM analysis using Image J programme. Prior to electrospinning, properties of solutions were measured, nanofiber diameter distributions were calculated and relationship between electrical conductivity and nanofiber average diameters was evaluated. In this study, we aimed to assess relation between solution properties and fiber diameter of produced nanofibrous mats. We obtained increased viscosity with increased solution concentration in our study; on the other hand there was not a proportional increase either in electrical conductivity or in surface tension of the solutions. Increasing solution viscosity gives higher nanofiber diameter; in our study we observed a general increase tendency in diameter; however, a diameter decrease from 14 wt % to 16 wt % increase in solution concentration is observed as well. We obtained 145.9 nm thickenesses in 16 wt % solutions and they were thinner than nanofibers produced from 14 wt % and 18 wt % solutions. Our fiber diameter averages show a tendency of being indirectly proportional with the exponential of electrical conductivity (1 / τe 0.1) compared to the mathematical formulation relationship stated in a previous literature study conducted by An et al. |
