The extent of water sorption in a thin film of a typical glassy polymer, poly(methyl methacrylate) (PMMA), was studied by neutron reflectivity. Interestingly, the as-spun film could uptake water to 16.3 vol%, much more than the reported value of a few vol% for bulk PMMA. This can be explained in terms of the heterogeneous density distribution in the film.
