Аннотация: The effects of modification of a silica matrix with organic groups, the order of mixing components in a sol-gel synthesis, and the magnitude of shear loading on the thixotropic properties of silica hydrogels were studied. All synthesized hydrogels were thixotropic and restored their structure by more than 90% within 1–3 min after shear load removal. The thixotropic properties of the organically modified hydrogels and the hydrogels prepared by adding a buffer solution (pH 7.4) to a silica sol were higher due to their stronger structures.

Ключевые слова: hydrogel, silica, modification, index of thixotropy, structural recovery.
