摘要：

研究了油酸对纳米二氧化钛(TiO$_{2})$改性后的纳米二氧化钛与聚甲基丙烯酸酯(poly (methl methacrylate/butyl methacrylate), P(MMA/BMA))聚合得到复合材料的性质.红外光谱、分散性能分析和接触角分析表征结果表明, 改性后二氧化钛疏水性增强. 采用双连续相微乳液法制备 TiO₂/P(MMA/BMA)复合材料, 并利用红外光谱表征 TiO₂ / P(MMA/BMA)复合材料. 由能谱仪(energy dispersive spectrometer, EDS)分析表明, 油酸改性纳米 TiO₂在复合材料中分散均匀, 并且讨论了二氧化钛添加量对产物热稳定性和紫外线屏蔽的影响, 随着 TiO₂含量的增加(最高5%), 热分解温度升高, 紫外吸收区域变强, 能阻挡400 nm以下的紫外光.

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.
