Preparation and characterization of flexible polyurethane foam nanocomposites reinforced by magnetic core-shell Fe3O4PTS nanoparticles

Novel magnetic polyurethane flexible foam nanocomposites were synthesized by incorporation of aminopropyltriethoxysilane (APTS) functionalized magnetite nanoparticles (MNPs) via one-shot method. The functionalized MNPs (Fe3O4PTS) were synthesized by co-precipitation of the Fe2+ and Fe3+ with NH4OH a...

Description
Summary:Novel magnetic polyurethane flexible foam nanocomposites were synthesized by incorporation of aminopropyltriethoxysilane (APTS) functionalized magnetite nanoparticles (MNPs) via one-shot method. The functionalized MNPs (Fe3O4PTS) were synthesized by co-precipitation of the Fe2+ and Fe3+ with NH4OH and further functionalization with APTS onto the surface of MNPs by sol-gel method. The magnetic core-shell NPs were used up to 3.0 % in the foam formulation and the magnetic nanocomposites prepared successfully. The results of thermogravimetric analysis (TGA) showed an increasing in thermal stability of polyurethane nanocomposite foam at initial, 5 and 10 %, and maximum thermal decomposition temperatures by incorporation of Fe3O4PTS. In addition SEM images revealed the uniformity of the foam structures and decreasing in pore sizes. Furthermore, VSM result showed super paramagnetic behavior for Fe3O4PTS-PU nanocomposites.
