A Study on the Surface Organic Modification of Aluminum Oxide and Its Dispersion Property in Polystyrene

    Graphical Abstract
    • Abstract
  • To enhance oil solubility of aluminum oxide, the surface organic modification of aluminum oxide particles with silane coupling agent KH 570 CH2C(CH3)COOC3H6Si(OCH3)3 was studied. The treated particles were dispersed in polystyrene as monomers' bulk polymerization. Fourier transform infrared spectrometer, X ray photoelectron spectra analysis and thermal analysis showed chemical bonds formed on the surface. The microstructure and properties of this composite were studied by means of SEM, which showed modified aluminum oxide particles dispersed more uniformly and in higher amounts than were unmodified ones.
