摘要/Abstract

摘要： 采用聚合物溶液浸润模板的物理方法，以聚酰胺酸溶液为前驱体，氧化铝膜为模板，制备了聚酰亚胺纳米线阵列，并用扫描电镜对纳米线阵列形貌进行表征.通过测量纳米线阵列的高度来表征聚合物溶液在纳米管中的流动距离，结果表明聚合物溶液在纳米尺度上的流动行为符合Lucas-Washburn方程.并探讨了聚合物溶液浓度对浸润机理及纳米结构形成的影响，有助于更好地控制模板中形成的纳米阵列结构.

Abstract: Polyimide nanowire array was fabricated by wetting alumina templates using polyamic acid solution. SEM was employed to characterize the morphology of nanowires. The flow distance of polymer solution in nanochannels was investigated by measuring the length of generated polymer nanowires, which demonstrates that the flow behaviour of polymer solution on nanoscale is in accordance with Lucas-Washburn equation. The influence of polymer solution concentration on the wetting mechanism and formed structures was discussed to help better control the nanostructure in the template.

Key words: template wetting method, polyimide, nanowires array, wetting mechanism
