静电纺丝法制备P（AN-co-VDC）纳米纤维的工艺研究
静电纺丝 P（AN-co-VDC） 纳米纤维
2014/7/17
通过静电纺丝技术制备了丙烯腈-偏氯乙烯共聚物[P（AN-co-VDC）]纳米纤维，针对纺丝过程中的工艺参数，详细考察了溶液浓度、施加电压和推进速率对纳米纤维形貌和直径的影响. 结果表明：溶液浓度对纤维的形貌和直径影响最大，电压和推进速率对其的影响相对较小；当溶液中聚合物质量分数为20%、电压为25 kV、推进速率为0.63 mL/h 时可获得表面光滑、形貌均一且直径较小的纳米纤维.
聚合方式对P(Am-co-VAc)浆料性能的影响
浆料 P(Am-co-VAc) 聚合方式
2009/10/23
以分散聚合和乳液聚合2种聚合方式分别合成P(Am-co-VAc)浆料,通过性能对比实验,研究这2种聚合方式对浆液的黏度、黏附性能以及浆膜性能的影响。结果表明:通过乳液聚合方式制备的P(Am-co-VAc)浆料大部分性能较好,其对纤维的黏附性能优于分散聚合型,浆膜的断裂强度、断裂伸长率及水溶性好于分散聚合型,浆膜吸湿性与之相似;乳液聚合方式有利于提高该类浆料的使用性能。
P(AM-co-AA)浆料的共聚组成对其黏附性能的影响
共聚组成 P(AM-co-AA)浆料
2009/10/20
以轻浆粗纱条的最大强力、断裂伸长和断裂功为量化指标,研究了P(AM-co-AA)浆料的共聚组成对其上浆涤/棉纱黏附性能的影响。所研究的聚丙烯酸类浆料包括P(AM-co-AA)及其相应的均聚物PAM和PAA,它们都是用相应的单体通过自由基引发剂引发的聚合反应制备。实验结果表明,这些浆料的共聚组成对其上浆涤/棉纱的黏附性能有显著影响,P(AM-co-AA)浆料的黏附性能显著优于均聚物PAM和PAA。
