摘要：Polystyrene (PS)/carbon black (CB) composite microspheres were prepared using a modified CB, which was prepared by blending CB with a hindered phenol antioxidant Irganox 1330 in an internal mixer. Scanning electron microscopy indicated that the modified CB adsorbed on the surface of PS microspheres homogenously to form a raspberry-like morphology composite. The non-covalent binding of Irganox 1330 on the surface of PS microsphere was observed from the UV-Vis absorption spectrum in ethanol, while the fluorescence of PS was almost totally quenched by the binding of Irganox 1330. These results implied there were aromatic interactions between Irganox 1330 and the PS microspheres, which played a crucial role in the formation of composite microspheres.
