Дослідження в’язкості золь-гель систем на основі тетраетоксисилану
The sol-gel systems of tetraethoxysilane (TEOS) – solvent – water systems at gelation viscosity dynamics has been investigated by means of viscosimetry. The influence of different factors (temperature, concentration of initial substances and the sol-gel process initiator) on the gelation rate has been established. The measurement of viscosity gradient dependence allowed to determine an elastic and friction components of viscosity using optimization method in the ORIGIN 5.0. program.
