The sol–gel process is a wet-chemical technique used for the fabrication of both glassy and ceramic materials. In this process, the sol (or solution) evolves gradually towards the formation of a gel-like network containing both a liquid phase and a solid phase.

2020年2月13日 · In this short tutorial, a fault-finding discussion based on the most common pictures drawn to illustrate the sol-to-gel transition has been used for a critical description of the process. Sol–gel transition is a critical phenomenon described by statistical models.

The sol-gel transition is the transformation of a sol, or colloidal solution, into a gel through the growth of links between particles, or molecular species, resulting in the development of a three-dimensional solid network.

2016年1月20日 · The sol-gel transition is often understood in the context of the lattice-based percolation model. Two parameters govern the sol-gel transition including the connectivity and polymer...

This book provides an in-depth introduction to the sol to gel transition in inorganic and hybrid organic-inorganic systems, one of the most important chemical-physical transitions and the basis of the sol-gel process.

tetra-PEG gel is a promising model system with high homogeneity and controllability. In this study, we investigated the sol-gel transition point as a function of connectivity and...

2020年6月1日 · The sol-gel transition is commonly discussed as a phase transition by qualitative analogy to vapor condensation. Here we show that the connection to thermodynamic phase transition...

Supramolecular gels can be designed such that pre-determined changes in state occur. For example, systems that go from a solution (sol) state to a gel state and then back to a sol state can be prepared using chemical processes to control the onset and duration of each change of state.

Investigating and understanding in detail the sol-to-gel transition in inorganic and hybrid systems is a very challenging task. The transition is a critical phenomenon that can only be described with statistical but not thermodynamic models.

Developed measurement complex allows obtaining rheological kinetic curves, from the beginning of sol-gel transition until complete conversion of the sol into a gel. Critical shear stresses in a wide range were measured.
