Effect of porous polymer films (track membranes) on the isothermal evaporation kinetics of water

Resumo

The kinetics of isothermal evaporation of distilled water that was in remote (10–15-mm) contact with porous polymer films (track membranes (TMs)) was studied by microgravimetry (derivatograph). When the H₂O–TM system contained a disperse medium, the supramolecular structure of water changed, and the number of clusters (coherent domains) drastically decreased. The extraction of the light phase from liquid water was correlated with the chemisorption of H₂O molecules containing the para-isomer of hydrogen, which predominantly form coherent domains of water.
