Comparison of the effects of an ionic liquid and other salts on the properties of electrospun fibers, 2 - poly(vinyl alcohol)
Understanding the effect of conductivity in electrospinning solutions is crucial in order to improve or control the electrospinning process. In this paper the effect of adding small amounts (0.039-0.2 59 mol . kg-1) of three different conductive additives to aqueous solutions of polyvinyl alcohol has been investigated. The salts were HMICl (a room temperature ionic liquid), TEBAC (a quaternary ammonium salt) and KC1. Addition of these salts causedasteadyincreaseinthesolutionconductivity but the fiber diameter was typically greater than that of PVA alone, and exhibited an oscillatory trend. The oscillatory trend on the fiber diameter is attributed to fiber backbuilding and fusion that occurs prior to deposition on the collector.© 2009 WILEY-VCH Verlag GmbH & Co. KGaA.
