  • Bijels And Methods Of Making The Same
    Publication number: 20220195171
    Abstract: A method of making a bijel includes dispersing surface-active nanoparticles in a ternary liquid mixture. The ternary liquid mixture includes a hydrophilic liquid, a hydrophobic liquid, and a solvent. The ternary liquid mixture is contacted with water. A bijel includes a stable mixture of two immiscible liquids separated by an interfacial layer of colloidal particles. The bijel has temperature-independent stability, and the domain sizes are below one micrometer.
    Type: Application

  • Polyelectrolyte microcapsules and methods of making the same
    Patent number: 11040324
    Abstract: Polyelectrolyte microcapsules, and methods for making and using the polyelectrolyte microcapsules, are described. A method of making polyelectrolyte microcapsules includes forming an “interfacial complexation in emulsion” (ICE), wherein a polyelectrolyte “shell” is formed by complexing two different polyelectrolytes together at an interface between two immiscible fluids. Both hydrophilic and hydrophobic materials can be incorporated into the cores and shells of the polyelectrolyte microcapsules.
