Abstract

This paper is a study on oleic acid-modified TiO2 nanoparticles and the incorporation of modified TiO2 nanoparticles into polyacrylate. The oleic acid is used to modify the TiO2 nanoparticles. From the Fourier transform-infrared spectroscopy (FT-IR) spectrum and the dispersity test, it can be seen that TiO2 nanoparticles enhance the hydrophobic after modification. The TiO2/poly (methyl methacrylate/butyl methacrylate) (P(MMA/BMA)) hybrid emulsion is prepared by bicontinuous microemulsion polymerization. In the FT-IR spectrum, the TiO2 characteristic peak appears. From the scanning electron microscopy (SEM) images and energy dispersive spectrometer (EDS) analyses spectrum, it is learned that the TiO2 nanoparticles are homogeneously dispersed in polyacrylate. The effect of addition amount of TiO2 nanoparticles on the thermal and the ultraviolet-shielding (UV-shielding) properties is discussed. With the increase of TiO2 content (maximum 5%), the TiO2/P (MMA/BMA) nanocomposites are thermally stable. Besides, it can block the UV light below 400 nm.

Key words： bicontinuous microemulsion; methyl methacrylate; butyl methacrylate; nano TiO2
