加入少量(1.0wt%)含氟聚合物后，聚二甲基硅氧烷/聚碳酸酯(α/PC)膜的透氧系数(Po2)和分离系数(Pn2)均有不同程度的提高。这种改善被认为是由于氧在表面积累的氟聚合物结构域中的选择性增溶所致。
Both oxygen permeability coefficient(PO2) and separation factor (α =PO2/PN2) through polydimethylsiloxane-b-polycarbonate(PDMS/PC) film were improved by the addition of small amounts(1.0 wt%) of the fluorine-containing polymer. This improvement was considered to be caused by the selective solubilization of oxygen in the surfaceaccumulated fluorine polymer domain.
