Gas Permeation of Sulfur Thin-Films and Potential as a Barrier Material

Elemental sulfur was formed into poly(ether sulfone)-supported thin-films (ca. 10 µm) via a melt-casting process. Observed permeabilities of C(2)H(4), CO(2), H(2), He, and N(2) through the sulphur thin-films were <1 barrer. The sulfur thin-films were observed to age over a period of ca. 15 days,...

Descripción
Sumario:Elemental sulfur was formed into poly(ether sulfone)-supported thin-films (ca. 10 µm) via a melt-casting process. Observed permeabilities of C(2)H(4), CO(2), H(2), He, and N(2) through the sulphur thin-films were <1 barrer. The sulfur thin-films were observed to age over a period of ca. 15 days, related to the reversion of polymerized sulfur to the S(8) allotrope. This structural conversion was observed to correlate with an increase in the permeability of all gases.
