| Popis: | A new method is described, which is used for determining kinetics of water vapour permeability and water vapour diffusion through porous and monolithic polymer materials and membranes. A report is given of methods of measuring and calculating water vapour transfer constants through sample. It was shown that using the method proposed increases accuracy and the information content of the experiment and enables main process parameters — coefficients of water vapour permeability, water vapour sorption and diffusion to be determined in one experiment. |
