Surface Chemical Modification and Characterization of Nano Fe₂O₃

Abstract:

The surface of nanoFe₂O₃ was modified with silane coupling agent 3-(methacryloyloxy) propyltrimethoxysilane (KH-570) under acidic conditions in order to improve the dispersity of particles in organic polymer and to enhance the interfacial bonding with the matrix. Contact angle measurement, thermogravimetric analysis (TG), Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD) were adopted to characterize and analyze the unmodified and modified nanoFe₂O₃. Through TG curves, it was calculated that when the KH-570 content was 25%, the grafting rate of Fe₂O₃ reached a maximum value at 7.28%. The FT-IR and XRD results indicated that KH-570 successfully modified the nanoFe₂O₃ with its organic functional groups chemically bonded on the surface of nanoFe₂O₃ which contributed to prevent particles from conglomerating. The surface treatment of nanoFe₂O₃ had no significant effect on the nanoparticles crystalline form. Contact angle measurement investigated that the hydrophile of modified nanoFe₂O₃ was decreased.
