This research focuses on developing improved methodologies for characterizing the degradation and predicting service lives of polymeric coatings, plastics, and sealants in all industries. Specific areas of research include (1) developing methodologies for service life prediction; (2) developing improved methods for characterization of polymeric materials and their degradation; (3) developing verifiable mathematical models to quantify degradation of coatings and related materials; (4) relating laboratory results with field data; (5) developing accelerated tests; (6) identifying the mechanisms and kinetics of degradation process under the influence of weathering elements, including ultraviolet, relative humidity, and temperature, and strain; (7) investigating photodegradation under different environmental and mechanical stresses; and (8) conducting in-situ measurement of water at the polymer/substrate interface. These studies provide essential quantitative data for predicting the performance and service lives of polymeric coatings, plastics, and sealants used in all industries.
