Surface tension Conductivity Dielectric constant Solvent volatility Electrostatic field shape Working distance Feed rate Orifice diameter Local atmosphere flow Atmospheric composition Pressure The importance of controlling these parameters is illustrated with the variation of polymer concentration. Thus, if the electrospinning process is carried out under low polymer concentrations, beads will be produced instead of fibres [87]. However, when the polymer concentration increases, the beads shape change to fibres as a consequence of higher viscosity and higher polymer entanglement [91]. In short, all the mentioned parameters can define the materials/fibres properties dramatically, from thin to thicker fibre diameters or to form smooth to wrinkle fibres. 4. Physical-chemical characterization of the membranes The physico-chemical characterization of polymer-based membranes encompasses the determination of a wide range of properties that allows to know the material itself and the expected performance when applied. Naturally, the type of application for which the membrane is intended for is the major factor in the selection of the characterization to be performed, in any case, there are a set of properties that are essential to know with respect to polymeric membranes regardless of the type of application. 14PDF Image | Synthetic Polymer-based Membrane for Lithium Ion
