This work is the first and unique comparative study on a so wide range of vapour activities and a so vast number of different techniques, giving important insight into the transport phenomena themselves and on how results are affected by the specific technique used. Results are demonstrated and discussed in detail on the basis of a pair of penetrants with different physico-chemical properties and molecular shape (toluene vs. heptane). Information about differences between concentration dependent permeation and sorption, coupling effect, molecular clustering and polymer-solvent interactions is reported as well.
Přehledný článek se zabývá transportem těkavých organických látek přes neporézní membánu. Výsledky jsou demostrovány a diskutovány detalně na základě permeujících látek s různými fyzikálně chemickými vlastnostmi.
