采用Langmuir-Blodgett （LB）技术在空气-水界面处制备了紫外聚合磷脂和共聚物纳米膜。采用氦离子显微镜（HIM）和原子力显微镜（AFM）分别在真空和常温条件下研究了独立和底物支撑的二维纳米膜。我们通过紫外线聚合1-棕榈酰-2-(10,12-三osadiynoyl)- n-甘油-3-磷酸乙醇胺（PTPE）和二嵌段共聚物聚丁二烯(1,2)-b-聚乙烯氧化物（PB-b-PEO）形成完整而坚固的2D纳米膜，能够形成至少8微米大小的独立膜。利用衰减全反射红外（ATR-IR）光谱对紫外光聚合的PTPE纳米膜进行进一步研究，可以监测聚合过程，观察到C=O吸收频率的变化以及紫外光诱导转换的其他特征信号的上升。
We prepared UV-polymerized phospholipid and copolymer nanomembranes at the air-water-interface by Langmuir-Blodgett (LB) technology. The freestanding as well as substrate-supported 2D nanomembranes were investigated in vacuum by helium-ion-microscopy (HIM) and under ambient condition with atomic force microscopy (AFM). We found intact and robust 2D nanomembranes by UV-polymerization of 1-palmitoyl-2-(10,12-tricosadiynoyl)-sn-glycero-3-phosphoethanolamine (PTPE) and by diblock copolymer polybutadiene(1,2)-b-polyethylene oxide (PB-b-PEO) formation that were able to form freestanding membranes with at least 8 µm in size. Further investigation of the UV-polymerized PTPE nanomembranes with attenuated total reflection infrared (ATR-IR) spectroscopy allowed us to monitor the polymerization process, where a shift in frequency of C=O absorption was observed together with the rise of other characteristic signals of the UV light-induced conversion.
