020. (Book and Paper) Cellulose Acetate Lamination: Composition and Condition

Log in to save this to your schedule and see who's attending!

Cellulose acetate lamination of paper documents was a common preservation/conservation treatment in the 20th century.  This treatment fell out of favor due to concerns over the stability of the cellulose acetate films used for lamination, the compositions of which changed over time.  However, many collections contain large numbers of cellulose acetate laminated documents.  This research evaluates how the chemical composition of these films today has impacted the overall condition of the laminated documents, using a combination of techniques.  Analyses with pyrolysis-gas chromatography/mass spectrometry, infrared spectroscopy, nuclear magnetic resonance spectrometry, surface pH testing and microscopy have been done to evaluate the composition of the lamination films today.  The results show trends in how composition of the films changed over time and how this composition has impacted the survival of these laminates.
