The results of Fourier transforminfrared spectroscopy???FTIR??????scanning electron microscopy???SEM???and energy dispersive X-ray energy spectroscopy???EDS???show that the nanoGd2O3wassuccessfully modified bycoupling reagent and the surface modificationof nanoGd2O3significantly improved the interfacial compatibility and dispersion in the polyethylene matrix |
