  • Publication number: 20130064759
    Abstract: An emulsion includes a substantially continuous liquid medium, and a plurality of droplet structures dispersed within the substantially continuous liquid medium. Each droplet structure of the plurality of droplet structures includes an outer droplet of a first liquid having an outer surface; an inner droplet of a second liquid within the first droplet, the second liquid being immiscible in the first liquid, wherein the inner and outer droplets have a boundary surface region therebetween; an outer layer of block copolymers disposed on the outer surface of the outer droplet; and an inner layer of block copolymers disposed on the boundary surface region between the outer and the inner droplets.
    Type: Application

  • Patent number: 8283308
    Abstract: An emulsion includes a substantially continuous liquid medium, and a plurality of droplet structures dispersed within the substantially continuous liquid medium. Each droplet structure of the plurality of droplet structures includes an outer droplet of a first liquid having an outer surface; an inner droplet of a second liquid having an inner surface contained within the outer surface of the outer droplet of the first liquid, the second liquid being immiscible in the first liquid, wherein the inner and outer droplets have a boundary surface region therebetween; an outer layer of block copolymers disposed on the outer surface of the outer droplet; and an inner layer of block copolymers disposed on the inner surface of the inner droplet. The block copolymers include a hydrophilic polymer block and a hydrophobic polymer block that act in combination to stabilize the droplet structure, and the first liquid is immiscible in the substantially continuous liquid medium.

  • Publication number: 20100010105
    Abstract: A method of producing an elastic material including providing a viscous material having an initial material composition thereof, the viscous material being a multiphase dispersion comprising a plurality of discrete elements of a first component dispersed within a continuous fluid phase of a second component; and applying stress to the plurality of discrete elements of the first component to break up the plurality of discrete elements into a second plurality of discrete elements having a greater number of discrete elements than the first plurality of discrete elements. The discrete elements of the second plurality of discrete elements have at least one of a composition or a surface layer that provides at least a repulsion between adjacent discrete elements to prevent the discrete elements from irreversibly coalescing or irreversibly re-uniting, the viscous material thus irreversibly becoming an elastic material having a same material composition as the initial material composition.
