초록

Poly(vinyl alcohol) (PVA) solutions were prepared by dissolving PVA in malic acid (MA)/distilled water, lactic acid (LA)/distilled water, and distilled water (DW) as a comparison solvent Viscosity and electric conductivity of PVA solution were determined by using a digital viscometer and electric conductivity' meter at room temperature, respectively. The morphological characteristics of the electrospun PVA nonwoven mats were investigated with a scanning electron microscopy (SEM) after gold sputtering. Also, mechanical properties of electrospun PVA nonwoven mats were measured by a universal testing machine (UTM). SEM results indicated that the electrospun fibers prepared from 4 wt% MA/DW as a solvent showed highly entangled structure due to their bent shape, which resulted in high mechanical strength of electrospun PVA nonwoven mats. Tensile strength and breaking elongation of electrospun PVA fibers prepared from 4 wt% MA/DW were over 12 MPa and 420%, respectively.
