Abstract

Small angle X-ray scattering was used to characterize the structure of sols and gels in the TMOS-MeOH-H2O-CHONH2 system. The scattering curves were analyzed in both the Porod and Guinier regions. A fractal analysis shows that the structure evolves with time and temperature from a linear type polymer to a more highly branched polymer and then towards a “particle”. However, these structural units disappear when the temperature increases above a critical value.
