  • Method of forming mesoscopically structured material
    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.
    Type: Grant
    Filed: May 14, 2002
    Date of Patent: March 21, 2006
    Inventors: Peidong Yang, Tao Deng, George M. Whitesides, Galen Stucky, Dongyaun Zhao, Bradley Chmelka, David Pine, Pingyun Feng
  • Method for forming hierarchically ordered porous oxides
    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.
    Type: Grant
