| 摘 要： | 以N，N-二甲基甲酰胺为溶剂，对不同比例的乙酸木质素（AAL）与聚乙烯吡咯烷酮（PVP）混合溶液，AAL与聚丙烯酸酯（polyacrylate）混合溶液，AAL与聚乙烯醇（PVA）混合溶液三种溶液体系进行静电纺丝。用扫描电子显微镜观察了纳米纤维的表面形貌。结果表明：AAL与PVA混合溶液通过电纺不能得到纳米纤维。通过电纺可以得到直径均匀、表面光滑的AAL与PVP混合纳米纤维，AAL与聚丙烯酸酯混合纳米纤维，并且AAL含量的增加对混合纳米纤维的直径和表面形貌没有明显的影响。进而对单一AAL的静电纺丝进行了研究，分别研究了THF，DMF，乙酸等不同的溶剂体系，发现只有以乙酸为溶剂才能电纺成纤。

| Abstract: | Different ratios of AAL/PVP blend solutions,AAL/polyacrylate blend solutions and AAL/PVA blend solution were prepared by dissolving in DMF and then used for electrospinning.Surface morphology of the nanofibers was characterized by scanning electron microscopy(SEM).Results showed that nanofibers can 't be obtained by electrospinning AAL/PVA blend solution,AAL/PVP blend nanofibers and AAL/polyacrylate blend nanofibers with smooth surfaces were obtained by electrospinning.The morphology structure and diameter ... |
