Characterization and Weathering of Motion-picture Films with Support of Cellulose Nitrate, Cellulose Acetate and Polyester

The microanalytical characterization of several motion-picture film samples of different support layers (cellulose nitrate, cellulose acetate and polyester) is presented. The goal of the work is to provide, by performing analyses and collecting data, a clear picture in order to better define the nature of the samples, their morphology, and any forms of degradation, by focusing on the causes and the mechanisms of weathering. To achieve these purposes several microanalitical techniques were used.
