ABSTRACT / САЖЕТАК:

Polyurethane composites based on polycaprolactone (PCL), Boltorn® aliphatic hyperbranched polyester of the second pseudo generation (BH-20) and isophorone diisocyanate (IPDI) and unmodified and surface modified TiO2 nanoparticles, were successfully prepared. The surface modification of TiO2 nanoparticles was performed with lauryl gallate (LG). The impact of added TiO2 nanoparticles and their content on the morphology of the polyurethane network (PU) were examined. The obtained results show that the addition of both, unmodified and modified TiO2 nanoparticles, has significant impact on the cross-sectional and surface morphology of PU.
