Previous studies have documented the dramatic effects of film thickness, at least compared to the bulk state, and the more modest effects of aging temperature and polymer structure on physical aging of thin glassy polymer films. In this paper, these results are interpreted in terms of the free volum

This paper describes methodologies that have been developed for studying the physical aging of free-standing thin polymer films and its effect on gas permeability. Both solution casting and spin coating methods were used to obtain thin polysulfone films having thicknesses in the range of 400-1000 nm
