Effect of ultraviolet radiation on transparent polymer films as determined using in situ FTIR-RA spectroscopy. Volume I. Photodegradation of transparent polymer films
This report demonstrates the application of Fourier transform infrared reflection-absorption (FTIR-RA) spectroscopy to the in-situ study of the effects of ultraviolet radiation on polymeric materials proposed for use in passive solar heating and cooling systems. The method permits collection of the infrared reflection-absorption spectrum of a polymer film on an IR-reflective substrate while the sample is exposed to simulated outdoor conditions. Preliminary studies of two materials (polycarbonate and poly(methyl methacrylate)) having potential for glazing applications are described. Qualitative information on photodegradation reaction mechanisms was obtained, and quantum yields for some reactions were determined and shown to be comparable to literature values.
