Preparation of ZrO₂-Silica Microspheres by Layer-by-Layer Self-Assemble Technique

Abstract:

The uniform nanoparticle multilayers micrometer-sized silica particle have been fabricated by consecutively assembling of surfactant C₁₂H₂₅SO₄Na (SDS) and nanoparticles onto Silica microspheres and subsequently removing the surfactant by calcinations. The samples were characterized by X-ray diffraction, FT-IR,TG and SEM. Presence of the FT-IR bands with frequencies ranging from 800 to 900 cm-1 can be assigned to Si–O vibration, and to Zr–O–Si stretching vibration. XRD analysis showed obviously the characteristic diffraction peaks of tetragonal (T-ZrO₂) and nanoscale of ZrO₂. The SEM image showed that the surface layers of silica microspheres were coated by nanoparticles.
