  • Patent number: 12371444
    Abstract: A method of synthesis of metal organic frameworks (“MOFs”) includes preparing a metal solution by dissolving at least one metal salt in an aqueous solution and buffering the metal solution with a base to achieve a first pH, the metal solution optionally comprising an organic co-solvent, preparing a linker solution by adding at least one organic acid linker and at least one base to an aqueous solution, and mixing the metal solution and the linker solution to produce the MOFs. The at least one organic acid linker has an ability to be protonated or deprotonated in response to a second pH, and the mixture of the metal solution and the linker solution has a third pH value, where the third pH value is greater than a highest pKa of the organic acid linker. The MOFs may be applied to a textile.

  • Publication number: 20240399336
    Abstract: Embodiments disclosed herein provide methods of making polymer-metal organic framework-gels (polymer-MOF-gels), the method comprising forming a metal solution comprising a metal salt, an acid, and a first solvent, and forming a product mixture comprising the metal solution, a polymer, and a carboxylic acid linker to produce the polymer-MOF-gel. Embodiments disclosed herein provide polymer-MOF-gels comprising a polymer and a metal organic framework (MOF) having pores, wherein at least a portion of the polymer is entrapped in the pores of the MOF.

  • Patent number: 9070881
    Abstract: A method of manufacturing an organic semiconductor thin film includes coating an organic semiconductor solution on a substrate, and shearing the organic semiconductor solution in a direction that results in a shearing stress being applied to the organic semiconductor solution to form the organic semiconductor thin film, wherein a speed of the shearing is controlled such that an intermolecular distance of the organic semiconductor solution is adjusted.

  • Publication number: 20150123105
    Abstract: Various aspects of the instant disclosure are directed to methods and to apparatuses involving spin-coating and spin-coated materials. As may be implemented in connection with one or more embodiments, a solution having objects dispersed therein is applied to a substrate and the substrate is spun about an axis that is off-center relative to a center of the substrate. The objects are thus aligned along a predominantly unidirectional orientation. The solution is solidified with the objects aligned to one another along the predominantly unidirectional orientation.
