제목 Improvement of Water-Resistance of Atactic Poly(vinyl alcohol) Nanoweb by Heat Treatment
초록 Nanoscale materials can be rationally designed to exhibit significantly improved physical, chemical, and biological properties, because of extremely small dimension. Among these nano-technologies, electrospinnig has attracted attention during the last several years as a simple and straightforward method. Electrospinning produces various fibrous materials with diameters in the sub-micron range by applying the external electric field imposed on a polymer solution or melt. An electric field is used to create a charged jet of polymer solution. As this jet travels in air, the solvent evaporates from a charged fiber that can be electrically deflected or collected on a metal target.
In this study, we prepared water-soluble atactic poly(vinyl alcohol) (PVA) nanoweb using electrospinning. Then, to improve water-resistance of PVA nanoweb prepared, the nanoweb was heat-treated at different treating temperature. The structure and properties of PVA nanoweb treated were investigated by scanning electron microscopy, differential scanning calorimetry, wide-angle X-ray diffractometer, and Instron.
