  • Publication number: 20070256978
    Abstract: Mesoscopically ordered, hydrothermally stable metal oxide-block copolymer composite or mesoporous materials are described herein that are formed by using amphiphilic block polymers which act as structure directing agents for the metal oxide in a self-assembling system.

  • Publication number: 20070248760
    Abstract: Mesostructured inorganic-organic materials, in the form of patterned films, monoliths, and fibers, can be prepared with controllable orientational ordering over macroscopic length scales. They are synthesized by controlling solvent removal rates across material interfaces, in conjunction with the rates of surfactant self-assembly and inorganic cross-linking and surface interactions. A method for controlling the rates and directions of solvent removal from a heterogeneous material synthesis mixture that allows the nucleation and directional alignment of self-assembling mesostructures to be controlled during synthesis is disclosed. The aligned mesostructured inorganic-organic materials and mesoporous inorganic or carbon materials can be prepared in the form of patterned films, monoliths, and fibers with controllable orientational ordering.

  • Publication number: 20070191499
    Abstract: Novel membranes based on functionalized porous inorganic materials for ion exchange and conduction have been synthesized and characterized. The preparation procedure of these new membranes involves the synthesis of porous inorganic films, into which hydrophilic moieties are incorporated along the interior pore surfaces of the inorganic framework. Ion-conducting species are grafted into the pores via reactions with surface groups of the inorganic framework to allow for ion transport through the pore network.

  • Patent number: 7014799
    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.

  • Patent number: 6716378
    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.
