Mapping Environmental Conditions That Prevent Plastic Deterioration While Contributing to Sustainable Preservation Environmental Management

This research project will study the relationship between equilibrium moisture content (EMC) and the physical stability of plastics and plastic composite artifacts found in museums. Objects such as modern and contemporary artworks, design, fashion, and ethnographic items often include plastics, as do the storage materials used for photographs. The project team will use multiple types of analyses, including a case study, to assess the effect of microscopic changes in humidity on the physical structure of two types of plastics commonly found in museum collections. The project will establish safe preservation and handling conditions for these plastics, specifically temperature and relative humidity. Findings will be shared through journal articles, conference presentations, and a web publication.
