文摘
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.
