  • MOF-clay-polymer composite membrane with dispersed filler constituents and anisotropically-oriented clay platelets
    Patent number: 12311322
    Abstract: A composite membrane and method of making the same, wherein the membrane includes a polymer component; an impermeable clay-platelet filler component; and a permeable metal-organic framework filler component combined with the polymer component and the impermeable clay-platelet filler component to form a film. The impermeable clay-platelet filler component includes an anisotropic orientation aligned parallel to a surface of the film. The polymer component includes polyethylene oxide. The polyethylene oxide includes a viscosity-averaged molecular weight of 106 g/mol. The impermeable clay-platelet filler component includes hydrous magnesium silicate clay. The permeable metal-organic framework filler component includes UiO-66-NH2. The film includes a water vapor transport rate of 35 g/m2/hr. The impermeable clay-platelet filler component includes an aspect ratio having a ratio of diameter to thickness of 10 to 1 or greater.
