Hydrophobic magnetic mesoporous microsphere as well as preparation method and application thereof

The invention belongs to the preparation field of organic-inorganic composite nanometer materials, in particular relates to a hydrophobic magnetic mesoporous microsphere as well as a preparation method and application thereof. The preparation process of the hydrophobic magnetic mesoporous microsphere is as follows: (1) with a surface active agent as a structure-directing agent, silicon dioxide/surface active agent composite materials, doped with hydrophobic groups and having ordered mesoporous structures, are coated on the surfaces of magnetic inorganic nanometer particles through the sol-gel reaction; (2) the surface active agent is removed through the solvent extraction to obtain the hydrophobic magnetic mesoporous microsphere. The prepared hydrophobic magnetic mesoporous microsphere has excellent nuclear-shell morphology, good magnetic field inductivity and strong specificity, and has excellent use value and potential application foreground in such fields as proteomics.
