Films of polyaniline (PANI) featuring about 80% crystallinity and characterised with strong π-π stacking alignment parallel to the film surface have been obtained directly after the original synthesis upon simple drying of the aqueous PANI suspension. A strong anisotropy in the growth of the nano-sized crystals produced during the synthesis results in the formation of micrometer-length fibrils perpendicular to the film surface in the course of water evaporation. The regular intercalation of water molecules between the PANI chains seems to be crucial for their ordering throughout the synthesis and film formation.
通过对聚苯胺（PANI）水悬浮液进行简单干燥，在原始合成后直接获得了结晶度约为80%且具有与薄膜表面平行的强π-π堆积排列特征的聚苯胺薄膜。合成过程中产生的纳米级晶体生长具有很强的各向异性，导致在水蒸发过程中形成垂直于薄膜表面的微米级长纤维。聚苯胺链之间水分子的规则嵌入似乎对于它们在整个合成和成膜过程中的有序排列至关重要。
