Appl. No.:

10/145658

International Classification:

B29C 6500

US Classification:

264 42, 264 43, 264 44, 264232, 264236, 264299, 264603, 264621

Abstract:

A low-cost, efficient method of preparing hierarchically ordered structures by filling a mold with a self-assembling mixture of hydrolyzed inorganic species and amphiphilic block copolymers and applying pressure to the mixture. Polymerization of the inorganic species within the mixture results in a mesoscopically structured material having molded features. A mesoporous material can be produced by subsequent thermal removal of the copolymers.

US Classification:

264 44, 264108, 264219, 264234, 264261, 264621

Abstract:

A low-cost, efficient method of preparing hierarchically ordered structures by filling a minimold with a microsphere-containing latex suspension, forming an close-packed array of microspheres within the minimold and filling void space in the array with a self-assembling mixture of hydrolyzed inorganic species and amphiphilic block copolymers. A macroporous and mesoporous material can be produced by subsequent thermal removal of the microspheres and copolymers.
