聚合物材料在许多科学和技术领域的应用不断增加，这促使聚合物表面处理得到广泛应用，这些处理改变了聚合物表面的物理和化学性质，导致表面活化以及表面粘附性的提高。傅里叶变换红外光谱椭圆偏振测量法（FTIRSE）和相位调制椭圆偏振测量法（PME）分别在红外和可见 - 远紫外光谱区域被用于对氩离子轰击所获得的聚合物表面结构变化进行原位和实时监测。这些聚合物是工业供应的聚对苯二甲酸乙二醇酯（PET）和聚萘二甲酸乙二醇酯（PEN）薄膜。研究发现氩离子轰击改变了薄膜的化学键，特别是C = O、C - C和C = C基团的数量。对FTIRSE光谱的详细研究揭示了氩离子轰击对上述每个键合基团影响的重要信息。此外，利用PME研究了PET和PEN大分子特定键中电子跃迁所导致的特征变化的改性。（C）2003爱思唯尔公司。保留所有权利。
The continuously increasing application of polymeric materials in many scientific and technological fields has motivated an extensive use of polymer surface treatments, which modify the physical and chemical properties of polymer surfaces leading to surface activation and promotion of the surface adhesion. Fourier transform IR spectroscopic ellipsometry (FTIRSE) and phase modulated ellipsometry (PME) in the IR and Vis-FUV spectral regions respectively have been employed for in situ and real time monitoring of the structural changes on the polymer surface obtained by Ar+ ion bombardment. The polymers were industrially supplied polyethylene tereplithalate (PET) and polyethylene naphthalate (PEN) membranes. The Ar+ ion bombardment has found to change the chemical bonding of the films and especially the amount of the C=O, C-C and C=C groups. The detailed study of the FTIRSE spectra reveals important information about the effect of the Ar+ ion bombardment on each of the above bonding groups. Also, the modification of the characteristic features, attributed to electronic transitions in specific bonds of PET and PEN macromolecules, has been studied using PME. (C) 2003 Elsevier B.V.
