以AAO膜为模板，采用挤出法制备了Nafion-115纳米线阵列。结果表明，AAO模板表面修饰前的真空处理对提高Nafion-115纳米线在AAO模板中的填充率起着重要作用，而Nafion-115 DMSO溶液的浓度对填充速率影响不大。研究了合成Nafion-115纳米线阵列的最佳工艺参数。在优化工艺条件下合成的AAO模板中Nafion-115纳米线的填充率约为95%。讨论了Nafion-115纳米线的生长机制，定性地解释了实验结果。
Nafion-115 nanowire arrays are synthesized with an extrusion method using AAO membranes as templates. It is indicated that the vacuum treating of AAO templates before surface decoration plays an important role in obtaining high filling rate of the Nafion-115 nanowires in the AAO templates, while the concentration of Nafion-115 DMSO solutions does not affect the filling rate greatly. The optimized parameters to synthesize the Nafion-115 nanowire arrays are studied. The filling rate of the Nafion-115 nanowires in the AAO templates synthesized with the optimized parameters is about 95%. The growth mechanism of Nafion-115 nanowires is discussed to qualitatively explain the experimental results.
