Electrospinning is a technique which produces fibres from a polymer solution exposed to an electric field. The technique forms fibres substantially smaller in diameter than a human hair. The action of an electric field on a sub-millimetre sized droplet results in a jet of polymer solution being ejected, and this is subjected to high electrostatic forces which elongate the jet and facilitate the removal of the solvent. This proposal aims to establish the way in which polymer chains in solution are transformed by the changes involved in this process. We shall look at the way polymer chains coil in solution by contrasting polymer solute molecules with hydrogen, and polymer solvent molecules in which the hydrogen has been replaced by deuterium. We shall compare the data for the polymer chain dimensions in solution with the dimensions of chains in fibres formed from the same polymer system.
