Structural and Surface Properties of Novel Polyurethane Films
In this work, novel polycarbonatediol- and polybutadienediol-based polyurethanes (PU) with promising properties were prepared and compared with an analogous polypropyleneglycol-based product. Hexamethylenediisocyanate was used as isocyanate (NCO) component. All three PU systems were
subsequently modified by the incorporation of two different nanofillers (Montmorillonite clays): “Cloisite 15A” and “Bentonite for organic systems.” The PUs were prepared in form of film coatings and characterized by atomic force microscopy (AFM), transmission electron
microscopy (TEM), and wide angle X-ray scattering (WAXS). Their chemical microstructure was checked by 13C-NMR spectroscopy.
