제목 Porous Yolk-Shelled SnO2 Microspheres with Porous Fe3O4 Core Through a Solvothermal Method and Its Application for Electromagnetic Wave
초록 Porous yolk shelled microspheres with porous Fe3O4 as a core material have been successfully prepared by combining the sol gel process and solvothermal deposition method and also controllability of the shell layers. The prepared p-Fe3O4@SnO2 yolk shell microspheres have the uniform size, well defined shells, high porosity and unique structure.

The characterization of the as prepared product was identified with field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), vibrating sample magnetometer (VSM) and N2 adsorption-desorption technique. The results indicate that the double shelled p-Fe3O4@SnO2 yolk shell microspheres have high surface area than the mono shell and p-Fe3O4.

For further application, these microspheres were mixing with paraffin wax and studied their electromagnetic properties. The excellent electromagnetic absorption properties may be attained to the unique p-Fe3O4@SnO2 double yolk shell microspheres and it’s may due to the synergistic effect between the magnetic core and dielectric SnO2 yolk shell. We believe the prepared p-Fe3O4@SnO2 yolk shell microspheres can be good candidates for electromagnetic absorbing materials.
