Patent number: 7399804Abstract: Intercalates and exfoliates formed from layered materials and dendritic polymers are disclosed, together with the uses of these materials, e.g. in producing composite materials. The dispersion of layered materials in a dendritic polymer matrix (hyperbranched polymers, star shaped polymers or star branched polymers) or has not been disclosed in the prior art. The high number of end-groups per molecule of dendritic polymer combined with their unique globular architectures leads to large intergallery spacings when intercalated in layered silicates and particularly facile exfoliation in spite of the high molar mass of the dendritic polymer. The excellent processability and potential high reactivity of dendritic polymers makes them extremely promising for thermoset applications, and coatings.Type: GrantFiled: August 13, 2002Date of Patent: July 15, 2008Assignee: Ecole Polytechnique Federale de LausanneInventors: Christopher Plummer, Laszlo Garamszegi, Yves Leterrier, Marlene Rodlert, Jan-Anders E.
