In this study, magnetic polyurethane (PU) elastomer nanocomposites were synthesized by incorporating Superparamagnetic Fe3O4@SiO2 nanoparticles into PU matrix through in situ polymerization method [1]. Fe3O4 nanoparticles were synthesized by co-precipitation of Fe+3 and Fe+2 as reaction substrates and NaOH as precipitant. The core–shell-structured nanoparticles (Fe3O4@SiO2) were prepared by sol–gel method [2]. effect of surface modification of Fe3O4 nanoparticles on thermal and mechanical properties of magnetic polyurethane elastomer nanocomposite was investigated. The samples were characterized by Fourier Transform Infrared Spectrophotometer(FT-IR) , Thermogravimetric analysis (TGA), and Vibrating Sample Magnetometer(VSM).The morphology and dispersion of the nanoparticles in the magnetic nanocomposites were studied by Scanning Electron Microscope(SEM).
