Measuring the x-ray irradiated degradation of PMMA through FTIR and 2D-COS analysis
- Los Alamos National Laboratory (LANL), Los Alamos, NM (United States)
To combat issues arising from polymer aging studies which include wasting valuable time and resources, Two-Dimensional Correlation Spectroscopy (2D-COS) has been observed to identify accelerated aging conditions in materials in a very short timeframe. This study is attempting to validate 2D-COS as a viable technique for aging studies by measuring the degradation of PMMA via x-ray radiation. PMMA has been previously observed to degrade via main chain scission under x-ray radiation, and similar results have possibly been seen in this study. More work needs to be done to collect reliable data, including finalizing a standard operating procedure and normalizing raw data so that noise is not recognized as spectral change by the extremely sensitive 2D-COS software.
