Abstract

Atactic poly(vinyl alcohols) (a‐PVAs) having number‐average degrees of polymerization [(Pn)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 characterization 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. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 93: 1638–1646, 2004

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
