  • Patent number: 9646735
    Abstract: The present disclosure provides advantageous graphene/graphite stabilized composites (e.g., graphene/graphite stabilized emulsion-templated foam composites), and improved methods for fabricating such graphene/graphite stabilized composites. More particularly, the present disclosure provides improved methods for fabricating pristine, graphene/graphite/polymer composite foams derived from emulsions stabilized by graphene/graphite kinetic trapping. In exemplary embodiments, the present disclosure provides that, instead of viewing the insolubility of pristine graphene/graphite as an obstacle to be overcome, it is utilized as a means to create or fabricate water/oil emulsions, with graphene/graphite stabilizing the spheres formed. These emulsions are then the frameworks used to make foam composites that have shown bulk conductivities up to about 2 S/m, as well as compressive moduli up to about 100 MPa and breaking strengths of over 1200 psi, with densities as low as about 0.25 g/cm3.

  • Patent number: 8288491
    Abstract: A process for producing high-quality polymer microparticles having uniform particle size of the order of several micrometers to tens of micrometers by inverse suspension polymerization at high productivity while keeping excellent dispersion stability without causing aggregation among particles. The inverse suspension polymerization involves a vinyl monomer and is performed in at least two steps. A water-soluble oxidizing agent and a water-soluble reducing agent are used as a polymerization initiator, and the water-soluble reducing agent is fed after the water-soluble oxidizing agent is fed.

  • Patent number: 8283385
    Abstract: Reversible switchable surfactants are provided. A surfactant is the salt of an amidine or guanidine: having at least one R group that is a hydrophobic moiety selected from the group consisting of higher aliphatic moiety, higher siloxyl moiety, higher aliphatic/siloxyl moiety, aliphatic/aryl moiety, siloxyl/aryl moiety, and aliphatic/siloxyl/aryl moiety. The other R groups are smaller moieties such as H, C1 to C4 aliphatic or the like. The surfactant is turned on by a gas that liberates hydrogen ions, such as, for example, carbon dioxide, which liberates hydrogen ions in the presence of water. The surfactant is turned off by exposure to a flushing gas and/or heating. When “on” the surfactants are useful to stabilize emulsions, and when “off” they are useful to separate immiscible liquids or a liquid and a solid. The surfactants find uses in polymerization and in the oil industry.

  • Patent number: 8273823
    Abstract: The invention is directed to a microemulsion polymerization comprising adding a polymerization catalyst precursor, such as a transition metal complex in the higher of two accessible oxidation states, an ATRP initiator, and an organic solvent to an aqueous solution to form an emulsion. Radically polymerizable monomers and a reducing agent may then be added to the emulsion. The reducing agent converts the catalyst precursor to a catalyst for polymerization of the first monomer from the initiator. In certain embodiments the organic solvent may comprise radically polymerizable monomers. The aqueous solution may comprise a surfactant.

  • Patent number: 8110628
    Abstract: Porous particles are prepared using a first water-in-oil emulsion comprising a first marker material in a first aqueous phase that is dispersed in a first oil phase containing a polymer and a first organic solvent, and a second water-in-oil emulsion comprising a second marker material in a second aqueous phase that is dispersed in a second oil phase. The first and second marker materials are detectably different. The two water-in-oil emulsions can be used to form a third water-in-oil emulsion containing distinct droplets of the first and second aqueous phases. This third water-in-oil emulsion is dispersed in a third aqueous phase containing a surface stabilizing agent to form a water-in-oil-in-water emulsion containing droplets of the third water-in-oil emulsion. The organic solvents are removed from the water-in-oil-in-water emulsion to form porous particles comprising first and second discrete pores that are isolated from each other.
