Microenvironments Studied for Next-Generation Suitability

摘要

Permeability, diffusion and solubility coefficients of oxygen gas and water vapor were measured for PC at 25℃. With similar molecular size, oxygen and water had similar diffusivity. However, water has a much greater affinity than oxygen does for PC, so water exhibited a faster permeation rate.rnThese inherent material properties were used to estimate the performance of an ME constructed from PC. Calculations gave realistic estimates of drying times in vacuum, breakthrough times, permeation rates and post-purge RH rise due to desorption from the ME materials of construction.
