[摘要] 这段文字主要介绍了如何确定氟聚合物表面的化学结构，特别是通过使用三种技术来研究一种名为Teflon PFA的氟聚合物薄膜的外表面。这些技术包括高分辨率电子能量损失光谱、相敏光声傅里叶变换红外光谱和飞行时间二次离子质谱。这些互补的技术证实，挤出过程会导致外表面受到少量污染，这可能是由于热挤出物在离开形成薄膜的模具时立即与大气发生反应所造成的。

[Abstract] Fluoropolymers are notoriously difficult to metallize. In order to ascertain the role of the substrate surface, the surface chemical structure of a representative fluoropolymer has been determined. Three techniques have been used to study the outer surfaces of the extruded fluoropolymer film, Teflon PFA. These techniques are: high-resolution electron energy-loss spectroscopy, phase-sensitive photoacoustic Fourier-transform infrared spectroscopy and time-of-flight secondary ion mass spectroscopy. These complementary techniques confirm that the extrusion process introduces a small amount of outer surface contamination, probably through the reaction of the hot extrudate with the atmosphere immediately on exiting the film-forming die.
