POLYVINYL ALCOHOL (PVA)

Polyvinyl alcohol for food use is an odourless and tasteless, translucent, white or cream colored granular powder. It is soluble in water, slightly soluble in ethanol, but insoluble in other organic solvents. Typically a 5% solution of polyvinyl alcohol exhibits a pH in the range of 5.0 to 6.5. Polyvinyl alcohol has a melting point of 180 to 190°C.

During emulsion electrospinning, jets are generated from the emulsion liquid, the dispersed drop in the emulsion makes the core of the electrospun fibres, while the continuous polymer matrix (here PVA) forms the shell [14,27]. This phenomenon is explained by the fact that water evaporates faster than oil whereby the polymer (PVA) solidifies faster than the oil drop (repellent) forming a shell around the oil drop.
