20.500.12556/RUL-172632 Difuzija acetona skozi PDMS-membrano Diffusion of acetone through PDMS membrane V diplomskem delu smo pri eksperimentalnem delu poskusili eksperimentalno določiti difuzivnost acetona skozi PDMS-membrano pri različnih podtlakih, vendar so bile meritve v nasprotju s pričakovanji in posledično določevanje difuzivnosti ni bilo izvedljivo. V nadaljevanju nam je uspešno uspelo matematično opisati potek difuzije acetona skozi PDMS-membrano v pretočnem stacionarnem sistemu. Uspelo nam je tudi grafično opisati parametrično odvisnost difuzijskega časa. In the experimental part of our thesis, we attempted to experimentally determine the diffusivity of acetone through a PDMS membrane under different vacuum conditions, however the measurements contradicted expectations, and consequently it was not possible to determine the diffusivity. On the other hand, we successfully managed to mathematically describe the process of acetone diffusion through a PDMS membrane in a flow-through steady-state system. We also successfully provided a graphical representation of the parametric dependence of the diffusion time.
