Abstract(#br)The solubility and diffusivity of several liquid species in crosslinked polydimethylsiloxane (PDMS) films were determined with a gravimetric method at 35\u003cce:hsp sp=\"0.25\"/\u003e°C. The series of liquids considered includes alkanes (from n-C 5 to n-C 18 ; cyclo-C 6 ), water, acetone, alcohols (ethanol, 1-propanol, 1-butanol, iso-butanol, tert-butanol, 1-pentanol, 1-hexanol), terpenes (squalene, limonene, linalool, geraniol) and edible oils with different oleic acid contents.

Abstract(#br)The multicomponent solubility of mixed liquid species in crosslinked poly(dimethyl siloxane) (PDMS) films was determined with a gravimetric method at 35\u003cce:hsp sp=\"0.25\"/\u003e°C. The series of binary liquid mixtures considered is formed by one non volatile and one volatile component: the latter can be acetone, n-pentane or tert-butanol. Acetone and n-pentane were mixed, separately, with vegetable oil and oleic acid; acetone has been also mixed with squalene and n-pentane with n-eicosane, while tert-butanol was mixed with poly (ethylene glycol) (PEG) 400.
