Effect of phase inversion approaches on morphology of polyurethane thin films

In this study, the effect of the phase inversion on thin films have been investigated.Asymmetric and symmetric polyurethane thin films were prepared by the wet and dry phase inversion method. For wet phase inversion, thin film was quenched in water. The prepared thin films were characterized with Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses for morphological comparison.
