The study of photodegradation stability of protective coatings used for cultural heritage materials by means of non-invasive and destructive analytical techniques.

The thesis aims to characterize the chemical, physical changes, and thermal stability of 12 different protective coatings used for cultural heritage after 5 months of artificial aging. Several non-invasive techniques were used like optical microscopy, colorimetry, static contact angle, FTIR. Furthermore, one invasive technique was used, TG-DSC for the characterization of the thermal stability of the samples. Finally, all the data were collected and compared after 5 months of aging to investigate the changes of the coatings.
