THE ETHYLENE CARBON-MONOXIDE COPOLYMER (CARILON) VIBRATIONAL-SPECTRA AND STUDY OF NANOMETER FILMS ON GOLD COVERED SUBSTRATE

Vibrational spectroscopy (IR, far IR), differential scanning calorimet ry and X-ray diffraction were used to study ethylene-carbon monoxide c opolymer ('Carilon') in the form of nanometer films on gold covered si licon substrates, thin films (approximate to 60 mu m) and plates (0.1- 0.2 mm). The Vibrational spectra of Carilon were calculated and interp reted using model normal coordinate analysis. This allowed to explain the IR spectra features of nanometer thickness Carilon films by compar ison with the bulk material (thin film and plate) by orientation of po lymer chains relative to metal surface and changes of the crystal stru cture of the films and chain conformation with thickness increase.
