Positron annihilation lifetime (PAL) spectroscopy has been employed to study subnanometer hole properties in polysulfone (PSF). In this study, hole properties of size, fraction, and distribution of PSF exposed to CO 2 are reported. In the PSF/CO 2 system, the hole size and fraction significantly inc
