Abstract
In a series of three papers we present the results of surface structure analysis of anisotropic polymer films using ATR-IR spectroscopy. In the first paper, the methodology for quantitative ATR-IR analysis of optically biaxial polymer films of orthorhombic symmetry is outlined, and results are presented of the first stage of the analysisthe extraction of the anisotropic optical constants of the films. Attention is drawn to the necessity that adequate sample/ATR-IR crystal contact is achieved in order to measure the correct reflectivity spectra of the sample/crystal interface and therefore obtain the correct (n, k) spectra of the analyzed film. The anisotropic absorption index spectra of PET and isotactic polypropylene films are presented in the 1800−670 and 1400−800 cm-1 range, respectively, along with the ATR-IR spectra from which the optical constants have been calculated. The extraction of all three principal absorption index spectra of PET films allowed us to examine the optical anisotropy of PET film...
