Block-copolyimide film from pPDA/ODA-PMDA was studied by TEM, SEM, PLM, ultra-deep three-dimensional microscope, TMA, and WAXD, which showed that the extensile strength and modulus of b-PI film were higher than that of irregular copolyimide film. It was also revealed that there was a large amount of crystallite formed in b-PI film, which was mainly attributed to its chain structure: rigid pPDA-PMDA chains were easy to form crystal nucleus because of phase separation, based on which semi-rigid PMDA-ODA molecular chains began to crystallize.

以pPDA／ODA-PMDA型嵌段共聚酰亚胺薄膜为对象，借助TEM、SEM、PLM、超景深三维显微镜、TMA、WAXD等手段，研究结果表明：b-PI薄膜的拉伸强度、弹性模量均高于无规共聚酰亚胺薄膜；b-PI薄膜中形成了大量的微晶，这是由于刚棒状的pPDA-PMDA分子链段因相分离容易形成晶核，然后半刚性的PMDA-ODA分子链段以PMDA-pPDA为晶核进行晶体生长造成的，而且ODA-PMDA分子链的结晶和酰亚胺化反应基本上是同步进行的。
