    摘要: A process of forming a composite material comprising treating pristine clay with water to form a swollen clay, intercalating the swollen clay with an organic solvent to form an organic solvent intercalated swollen clay by exchanging the water with the organic solvent while maintaining the swollen clay in a swollen state with the solvent. The organic solvent intercalated swollen clay is then treated with a silane coupling agent and the organic solvent intercalated swollen clay so modified is mixed with an epoxy matrix material to form a nanocomposite. The nanocomposite is then applied to a reinforcing material to thereby form a composite material.

    摘要: A process for forming a composite film on a substrate comprises providing a suspension comprising an ionised polymer and functionalised carbon nanotubes in a solvent, at least partially immersing the substrate and a counterelectrode in the suspension, and applying a voltage between the substrate and the counterelectrode so as to form the composite film on the substrate. Electrical charges on the polymer and on the nanotubes have the same sign and the voltage is applied such that the charge on the substrate has the opposite sign to the charge on the polymer and the nanotubes.

    摘要: A composition is provided, which comprises chains comprising a first graft copolymer of a first elastomer and a poly(L-lactic acid), and chains comprising a second graft copolymer of a second elastomer and a poly(D-lactic acid). At least some of the poly(L-lactic acid) and poly(D-lactic acid) crosslink the chains. Poly(L-lactic acid) and poly(D-lactic acid) may form stereocomplexes that crosslink the chains. The chains may be crosslinked by crystalline structures formed from at least some of the poly(L-lactic acid) and poly(D-lactic acid) in discrete regions. The crosslinked chains may form a matrix. In a method of forming the composition, the first and second graft copolymers are mixed, such as by melt blending or solution casting, to form the composition. The graft copolymers may be formed by a “grafting-though” or “grafting-from” process. The composition may be useful under a relatively wide range of temperatures.

    摘要: A copolymer for modifying rheology is formed of monomer units consisting essentially of at least one first monomer unit comprising a polyhedral oligomeric silsesquioxane having an ethylenically unsaturated radical; at least one second monomer unit comprising an unsaturated oligo-poly(dimethyl siloxane)(meth)acrylate; and a sufficient amount of at least one unsaturated water-soluble monomer, such that the copolymer is soluble in water. A composition may comprise an electrolyte and the copolymer. The rheology of an environment comprising an electrolyte may be modified by adding the copolymer to the environment.

The matrix polymer may include functional groups reactive with the carrier plastics compound to form a copolymer or a copolymer having at least one region thermodynamically miscible with said matrix polymer and at least one functional group reactive with said reactive carrier plastics compound to form a block copolymer therebetween.
