  摘要：

  开展了一项关于芳香族聚酰亚胺薄膜在不同对齐表面上合成和原位取向的组合研究。通过采用包含不同厚度的步进梯度、不同组成的扇区以及带或不带对齐层的扇区的组合方法制备的单体和聚酰亚胺库进行了调查。作为对齐表面，使用了摩擦沉积的PTFE层、摩擦处理的聚酰亚胺薄膜以及通过剪切技术制备的高度取向的聚酰亚胺层。除了3,3′,4,4′-联苯二酐（BPDA）外，只使用了具有不同纵横比的对位连接的二酐和二胺。首先通过单体蒸镀，然后顺序或同时蒸镀两种或更多单体来进行蒸镀。通过使用这种组合方法，可以通过变化单体组成、薄膜厚度和沉积顺序来优化单体和聚酰亚胺的取向。所得到的薄膜通过偏振FTIR和UV-Vis光谱在厚度以及达到的取向程度上进行了表征。在PTFE表面上的4,4″-二氨基对四联苯中观察到了通过二色比表示的最高取向度，其值为九到十。对于其他单体，不论对齐表面如何，确定的二色比约为二，表明取向度较低。研究结果发现，同时蒸镀两种单体产生具有良好品质的各向同性聚酰亚胺薄膜，而顺序蒸镀单体对则产生具有各向异性特性的聚酰亚胺薄膜。
