Abstract

MgO-CuO-CaO composites were synthesized by microwave hydrothermal using MgCl2·6H2O,CuCl2·2H2O and CaCl2 as raw materials and CTAB as dispersant.The structures of the samples were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),nitrogen adsorption(BET) and other characterization methods.The minimal inhibitory concentration(MIC) and colony count method were used to test the antibacterial properties of the samples.The results showed that MgO-CuO-CaO composites were nanoflake structure.The prepared MgO0.7CuO0.1CaO0.2 had a specific surface area of 66.789 m2/g,an average pore diameter of 54.117 nm and a pore volume of 0.904 cm3/(g·nm).MgO0.7CuO0.1CaO0.2 showed excellent antibacterial properties at the concentration of 500 μg/mL,and the antibacterial rate reached more than 99.9% at the concentration of 600 μg/mL.
