摘要
分析了介孔复合材料的原材料、中间产品及最终产品的傅里叶变换红外光谱图和X射线衍射图,得出材料制备过程中有机及无机组分定性及定量变化.结合透射电镜观测结果提出了介孔复合材料制备过程中组分变化机理,从作用力和热力学角度分析了有机离子载入反应的驱动力种类及作用机制.
The organic and inorganic component transformation of a mesoporous composite material in preparation process was an- alyzed based on the infrared spectrograms and X-ray diffraction patterns of raw materials, semifinished products, and end products. The change of components and their rations in the material were educed to judge the crystal lattice change of organic ion exchanged products. A transformation mechanism of components in the material was proposed according to FTIR analysis, X-ray analysis and TEM analysis. Driving force species and their alteration mechanism for the organic ion exchanging reaction were postulated from the view points of acting force and thermodynamics.
