采用静电纺丝法制备了纳米级交联聚乙烯醇PVA纤维。这项研究描述了其静电纺丝工艺、结构和过滤应用。发现纤维可通过马来酸有效交联。硫酸在交联过程中用作催化剂活化剂。采用扫描电镜、差示扫描量热技术以及红外反射吸收光谱（FTIR）对PVA纤维、PVA纤维以及PVA粉末的交联形态和结构进行了表征。此外，还测试了交联PVA纳米纤维的过滤性能。在实验过程中，将不同面积重量的交联PVA纳米纤维层放置在纺粘或熔喷子层上。结果表明，当子层中添加交联PVA纳米纤维层时，过滤效率急剧增加。 (C) 2008 年 Wiley 期刊公司。
Nanoscaled crosslinked poly(vinyl alcohol) PVA fibers were prepared by electrospinning. This study described its electrospinning process, structure, and filtration applications. The fibers were found to be efficiently crosslinked by maleic acid. Vitriolic acid was used as a catalyst activator during crosslinking. Scanning electron micrograph and differential scanning calorimetric techniques as well as infrared reflection-absorption spectroscopy (FTIR) were employed to characterize the morphology and structure of crosslinking of PVA fibers, PVA fibers as well as PVA powder. Moreover, the filtration properties of crosslinked PVA nanofibers were tested. During the experiments, crosslinked PVA nanofibers layers with different area weight were placed on the spunbond or meltblown sublayers. The result shows that the filtration efficiency increases sharply when crosslinked PVA nanofibers layers were added to the sublayers. (C) 2008 Wiley Periodicals, Inc.
