The pure gas test at 25 C revealed that J N2 was increased to 2.58 GPU, and α N2/SF6 was approximately 41, very close to the value in the literature [J. Mer. Sci., 2014, 452, 311]. Without the restriction from the usual PDMS coating layer for defect-blocking, the elevated temperature operation was able to be employed to further enhance gas permeation.
