Abstract in another language
We demonstrate the effect of confinement on the thickness-dependent swelling behavior of poly(styrene)-b-poly(2-vinylpyridine) diblock copolymer films as revealed by in situspectroscopic ellipsometry. "Microscopic" molecular confinement to the dimension smaller than the characteristic lamella spacing, as well as to the non-equilibrium microstructures limits the solvent up-take by the polymer film. The maximum degree of swelling ("macroscopic response") is achieved for films with a starting thickness in a dry state hdr in the range of [similar]one-two characteristic lamella dimension in bulk L0 and drops down according to [similar]hdr-0.1 as the film thickness increases up to [similar][small mu ]m scale ([similar]tens of L0). These findings bring novel fundamental insights into the stimuli-responsive behavior of confined soft matter.
