Abstract

Superfine powders of poly (methyl methacrylate) (PMMA) have been prepared by means of an emulsion polymerization method. These have been used as templates in the synthesis of tetragonal phase mesoporous zirconia by the sol-gel method, using zirconium oxychloride and oxalic acid as raw materials. The products have been characterized by infrared spectroscopy, X-ray diffraction analysis, transmission electron microscopy, N2adsorption-desorption isotherms, and pore size distribution. The results indicate that the average pore size was found to be 3.7 nm.

摘要

通过乳液聚合方法制备了聚甲基丙烯酸甲酯(PMMA)的超细粉末。这些超细粉末被用作模板,通过溶胶-凝胶法使用氧氯化锆和草酸作为原料合成四方相介孔氧化锆。通过红外光谱、X 射线衍射分析、透射电子显微镜、N2 吸附-解吸等温线和孔径分布对产物进行了表征。结果表明,平均孔径为 3.7nm。
