| Abstract: | The organic and inorganic component transformation of a mesoporous composite material in preparation process was analyzed 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 analysi... |
