卵磷脂是一种生物材料，在一定浓度的水中表现为溶性液晶形式。具体来说，卵磷脂形成类似于近晶相层的层状结构。我们描述了聚苯胺（PANI）、聚乙二氧噻吩（PEDOT）和聚吡咯（PPy）等聚合物在卵磷脂液晶基质中的电氧化制备。在交叉Nicol条件下，用偏光显微镜观察所得聚合物薄膜的片层结构的十字形图像（马耳他十字）。在电聚合过程中，卵磷脂在水中的层状结构被转录成合成的聚合物。本研究展示了通过电化学过程将生物材料的液晶聚集形式转录到合成聚合物上。
Lecithin is a biological material that exhibits lyotropic liquid crystal form at certain concentrations in water. Specifically, lecithin forms lamellar structures like a smectic phase layers. We describe electro-oxidative preparation of polymers such as polyaniline (PANI), poly(ethylenedioxythiophene) (PEDOT), and polypyrrole (PPy) in a lecithin liquid crystal matrix. Cross-shaped images (Maltese crosses) derived from lamellar structures were observed for the resultant polymer film with a polarizing optical microscopy under crossed Nicol condition. Lecithin lamellar structure in the water was transcribed to the resultant polymers during the electropolymerization. This research demonstrates transcription of a liquid crystal aggregation form of biomaterials onto synthetic polymers through electrochemical process.
