Preparation and Characterization of Polysiloxane@CeO2@PMMA Hybrid Nano/Microspheres via In Situ One-Pot Process

In this study, polysiloxane@CeO₂@PMMA microspheres were successfully synthesized by controllable one-pot process, in which CeO₂ nanoparticles were stabilized in the surface of PMMA nano/microsphere using an in situ precipitation method. The core–shell structure of the synthesized product were confirmed by FT-IR, XRD and electronic microscope analysis. The size of polysiloxane@CeO₂@PMMA nano/microspheres were about 550 nm via microscopy analysis. Moreover, the novel hybrid nanocomposites eliminated the yellowish coloration problem of CeO₂ and had good dispersibility. In addition, the transmittance of the multifunctional films based on polysiloxane@CeO₂@PMMA microspheres owned good transmittance of visible light and can block harmful UV rays, which can be attributed to nano-CeO₂ accession. Hence, such green synthesized route can be considered as a simple common method for preparing UV-shielding multifunctional materials.
