The effect of TiO2 particles on thermal properties of polycarbonate-based polyurethane nanocomposite films

In this work, aliphatic starting reactants were used to prepare a series of polycarbonate-based polyurethane (PC-PU) nanocomposite films with a low amount of titanium dioxide (TiO2) nanoparticles (0.5, 1.0 and 2.0%) by one-step technique. The influence of nanoparticles on the structure and hydrogen bonding, as well as the microphase and topography of the obtained hybrid materials was followed by Fourier transform infrared spectroscopy, Atomic...
