Abstract

Summary: Brillouin light scattering (BLS) from submicron-size patterned polyurethane (PU) films was found to display rich spectral features. Their identification allows the determination of the mechanical properties of the PU and the characterization of the periodicity and the coherence of the structure. A temperature-dependent study demonstrates that BLS is a sensitive tool to monitor changes of the mechanical properties and/or of the morphology.
