利用p偏振反射和调制偏振技术，获得了厚度在1 ~ 1000 nm的金属和二氧化硅表面上的聚全氟醚薄膜的红外光谱。振动峰的频率和相对强度随薄膜厚度的变化表明，液体聚合物在表面上的构象与体构象不同，聚合物链优先沿着表面延伸。
Infrared spectra of thin films of polyperfluoroethers on metal and silicon dioxide surfaces were obtained for films with thicknesses between 1 and 1000 nm by p‐polarized reflection and modulated polarization techniques. Changes in frequencies and relative intensities of vibrational peaks with film thickness suggest that the conformation of liquid polymers on surfaces is unlike bulk conformation, with polymer chains extended preferentially along the surface.
