Abstract

Atactic poly(vinyl alcohols) (a-PVAs) having number-average degrees of polymerization [(P_n)s] of 1700 and 4000 were prepared by the solution polymerization of vinyl acetate, which was followed by the saponification of poly(vinyl acetate) to investigate the effects of molecular weights of a-PVA on the characteristics of electrospun a-PVA nanofabrics. A-PVA nanofabrics were prepared by electrospinning with controlling the process parameters including the electrical field, conductivity, tip-to-collector distance, and solution concentration. Through a series of char-acterization experiments, we identified that the molecular weight of a-PVA had a marked influence on the structure and properties of nanofabrics produced. That is, the higher the molecular weight of PVA, the superior the physical properties of PVA nanofabric.
