对于100 nm厚的旋涂共聚物膜，证实了聚（偏二氟乙烯三氟乙烯）P（VDF-TrFE）的铁电β。借助X射线光电子能谱（XPS）研究了共聚物膜的均匀覆盖性。最重要的是，在共聚物的结晶相中存在的带隙直接由电子能量损失谱（EELS）确定。
The ferroelectric beta of poly(vinylidene fluoride trifluoroethylene), P(VDF-TrFE) is confirmed for 100 nm thickness spin coated copolymer film. The homogeneous coverage of the copolymer film is investigated by the help of X-ray photoelectron spectroscopy (XPS). Most importantly, the existing bandgap in the crystalline phase of the copolymer is determined directly from the electron energy loss spectroscopy (EELS).
