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.

This invention relates to malienated derivatives made from maleic anhydride, functionalized monomers, and one or more additional reagents, e.g., an oxygen-containing reagent (e.g., alcohol, polyol), a nitrogen-containing reagent (e.g., amine, polyamine, aminoalcohol), a metal and/or a metal compound. The invention relates to lubricants, functional fluids, fuels, dispersants, detergents and functional compositions (e.g., cleaning solutions, food compositions, etc.)

The invention provides novel surface coatings having surface polymer brushes with zwitterionic and antibiotics-conjugated side chains and synergistic anti-fouling and bactericidal properties. The surface coatings may be prepared using highly efficient surface-initiated living polymerization. The design of the surface polymer brushes are highly modular, allowing independent tuning of the anti-fouling and bactericidal properties, e.g., by varying the chemical nature of the zwitterionic motif and the antibiotic agent, the chemistry through which the antibiotic agent is conjugated to the polymer side chains, the molecular weight of the polymer brushes (e.g., thickness of coating and density of respective functional motifs), and the spatial arrangement of the respective functional motifs (e.g., homopolymers, block copolymers, random copolymers) to achieve optimal and sustained anti-infection outcome for a given application.
