  • Patent number: 8629200
    Abstract: The present invention provides an organic/inorganic compositive dispersant and a method for producing the same. The compositive dispersant comprises a complex of inorganic clay and an organic surfactant. The compositive dispersant is produced by reacting inorganic clay with the organic surfactant in a solvent to generate a complex. The inorganic clay is layered or platelet. The organic surfactant is an anionic surfactant such as alkyl sulfates, or a nonionic surfactant such as octylphenol polyethoxylate and polyoxyethylene alkyl ether. The compositive dispersant may be used to produce electrolytes of a solar cell or to increase the hardness of an epoxy resin.

  • Publication number: 20120171449
    Abstract: To produce an anti-flame film, nanoscale silicate platelets (NSP) are first diluted with water or an organic solvent; the dispersion is then dried on a surface to remove the water or organic solvent and finally an almost inorganic and flexible film with a thickness of 1 to 1,000 ?m is obtained. The film has a regularly layered alignment of primary platelet (1 nm thickness) structure. The NSP film has excellent anti-flame and heat insulation properties that can effectively shield a flame of more than 800° C. without apparent deformation in shape. The NSP can be blended with polymers with a composition over 30% or preferably 70% of NSP to make composite films with significant improvement in flame and heat shielding.

  • Patent number: 8168698
    Abstract: A method for producing random form of nanosilicate platelets comprises mixing and acidifying an exfoliating agent with an inorganic acid to form an acidified exfoliating agent; intercalating layered inorganic silicate clay with the acidified exfoliating agent to form a mixture; and dissolving the mixture in a solvent and reacting it with a hydroxide or chloride of alkali metal or alkaline-earth metal. The hyperbranched polyamines serving as the exfoliating agent are prepared by polymerizing poly(oxypropylene)-triamine and diglycidyl ether of bisphenol-A (DGEBA). Hydrophilic amine groups of the exfoliating agent are acidified and then reacted with the layered inorganic silicate clay through cation exchange reaction and physical clay exfoliation to give random form of nanosilicate platelets.
