Abstract

The main aim of the present work is to study the relationship between the synthesis-structure-property triangle of hybrid polymer materials. The investigations have been focused on the effect of synthesis parameters and on the materials structures over the atomic and supramolecular range. An important task was to improve the strength of the low-density aluminum- and silicon-containing oxide systems produced by sol-gel technology. The addition of organic polymers (e.g. PDMS) to the inorganic component increased the strength of the aluminosilicate aerogels two- or eightfold depending on the preparation conditions. The parameters of the synthesis had a strong influence on the structure, the structural parameters such as porosity, or even on the location of the aluminum atoms in the gel structure. The application of oligomeric inorganic particles resulted in a more homogeneous gel structure than that of monomer inorganic precursors (aluminum nitrate and TEOS). In the samples produced from oligomeric aluminosilicate particles, a fractal structure with high aluminum incorporation has been dominant. The structure obtained from monomer inorganic precursors has been built up from weak associates of aggregates. The elasticity and the homogeneity of the gel samples increased by treatment with some excess TEOS before the gel point.
