The permeability coefficients of O 2 , N 2 , and CO 2 gases at 25ยฐC were examined for composite membranes that were prepared by filling poly(ethylene oxide)(PEO) with different molecular weights into a porous membrane. The permeability coefficients of O 2 , N 2 , and CO 2 were 2 ฯซ 10 ฯช10 -4 ฯซ 10 ฯช10
Poly(dimethylsiloxane) (PDMS) and aromatic polyamide (aramid) multiblock copolymer (PAS) membranes containing ยฎ55 wt % of PDMS were prepared. Their tensile strength, morphology, and oxygen permeation property were investigated. The observed high tensile strength of PAS with 55 wt % of PDMS indicates
