Preparation and swelling properties of polyurethane/TiO2 nanocomposites
Апстракт
Polyurethane/TiO2 nanocomposites (NCs) were fabricated from environmentally friendly
polyurethane (PU) network, based on polycaprolactone (PCL) and Boltorn® aliphatic
hyperbranched polyester of the second pseudo generation (BH-20) as crosslinking agent, and
unmodified and surface modified TiO2 nanoparticles (NPs). The surface modification of TiO2 NPs
was done with lauryl gallate. The chemical structure of the prepared PU/TiO2 NCs was studied by
Fourier transform infrared spectroscopy (FTIR), while their amorphous nature was confirmed by Xray diffraction (XRD). The influence of type and content of the applied TiO2 NPs on swelling
properties in toluene and tetrahydrofuran (THF) and on water absorption of the prepared PU/TiO2
NCs were investigated. The obtained results revealed that swelling behavior depends on the used
solvent, while percentage of absorbed water decreases with increasing content of TiO2 NPs and it is generally lower in NCs prepared with modified TiO2 NPs.
