Abstract
PANI films were deposited on glass substrates by in-situ polymerization
and characterized by UV-VIS spectroscopy and atomic force microscopy. A
method is developed to accurately analyze ellipsometric data obtained for
transparent glass substrates before and after modification with absorbing polymer
films. Surface modification was made with an overlayer such as polyaniline (PANI),
which exhibits different optical properties by varying its oxidation state. First, the
issue of using transparent substrates for ellipsometry studies was examined and
then, spectroscopic ellipsometry was used to characterize absorbing overlayers on
transparent glasses. The same methodologies of data analysis can be also applied
to other absorbing films on transparent substrates, and deposited by different
techniques.
