| 摘 要： | 实验探究氨基乙酸型高分子纺丝溶液的组成，考察纺丝条件（电压强度、流速和接收距离等因素）与纳米纤维膜形貌的关系，并进一步研究交联处理对纳米纤维形貌和溶失率的影响。结果表明，在纺丝电压为24 kV、流速为0.5 mL/h、接收距离为8.0 cm的纺丝条件下获得的纳米纤维直径分布均匀，形貌较为良好，平均直径为（150±77）nm；经过戊二醛蒸汽预交联和环氧氯丙烷二次交联的纤维在水溶液中的稳定性显著提高，溶失率降低至4.31%，且纤维的形貌保持良好。 |

| Abstract： | In this study, the composition of imido-acetic acid type polymer spinning solution was investigated, and the influences of spinning conditions (voltage intensity, velocity and distance between syringe needle and drum) on the morphology of nanofiber were also investigated. Furthermore, the effect of crosslinking on the morphology and dissolve-loss percentage of nanofibers were also investigated. The results showed that the average diameter of nanofibers was (150±77) nm, with uniform diameter distribution and relatively good morphology, when the optimized conditions of voltage 24 kV, working distance 8.0 cm, flowing rate 0.5 mL/h were applied. And the stability of nanofibers in the aqueous solution was improved, where the dissolve-loss percentage of nanofibers was considerably decreased to 4.31%, without significantly change in morphology, when pre-crosslinked with glutaraldehyde vapor and cross-linked with epichlorohydrin. |
