Effect of Rheological Properties on Electrospinning of Ultra High Molecular Weight (UHMW) Poly(vinyl alcohol)
The effects of rheological properties on the electrospun fiber structure of polyvinyl alcohol (PVA) with ultra high molecular weight (UHMW) and high hydrolysis degree have been studied in this article. A hydrazine salt was used to modify the rheological properties of PVA aqueous solution in order to facilitate electrospinning. Rheological properties of the solution and fiber morphology were investigated by a rheometer and a scanning electron microscope respectively. The results show that it is impossible for the pure PVA solution to electro spin. But at the presence of hydrazine salt,the apparent viscosity of PVA solution decreased with storage time increasing and nano fibers can be fabricated by electrospinning. Furthermore,the diameters of electrospun fibers also reduced with viscosity decreased.
