| Description
| - Conducting polymers are nowadays in forefront of the interest because of its very good electrical conductivity combined with other beneficial properties. Polyaniline is one of the widely studied conducting polymers due to its light weight, low cost, excellent environmental stability and reversible acid-base switching of its electrical conductivity. This study is focused of polyaniline thin films prepared from anilinium sulfate by its chemical polymerization using ammonium peroxodisulfate. During the polymerization process, polyaniline was deposited on glass slides where it formed thin film. Different polymerization times were used (10, 20, 30 and 40 minutes). Two sets of polyaniline thin films were prepared. The first set was kept in dry in desiccator; the second set was freely exposed to air moisture. Influence of storage to protonation state of polyaniline films was revealed after long time observation. Samples kept in desiccator hold longer its protonation state as well as its color, which is the marker of protonation state. Protonation is also dependent on the polymerizations time, longer polymerization time leads to better protonation of polyaniline film. Raman spectroscopy, which is sensitive to chemical bonds and changes in structure, was used for the characterization of protonation state.
