Minimal conditions for solidification and thermal processing of colloidal gels.
Proc Natl Acad Sci U S A
June 2023
Colloidal gelation is used to form processable soft solids from a wide range of functional materials. Although multiple gelation routes are known to create gels of different types, the microscopic processes during gelation that differentiate them remain murky. A fundamental question is how the thermodynamic quench influences the microscopic driving forces of gelation, and determines the threshold or minimal conditions where gels form.

- Modulating the interaction potential between colloids can lead to phase changes and non-equilibrium states, essential for studying microscopic behaviors in these systems.
- Current methods fail to predict equilibrium and non-equilibrium phenomena for systems with longer-ranged interactions, highlighting a need for better approaches to understand interaction potentials.
- The study uses a kinetics-based algorithm to identify conditions for colloidal gelation by analyzing how interaction potential shape and thermal quench rate affect non-equilibrium states, providing a new way to match simulations with experimental results.
