International Classification:

B01D 71/02
B01D 69/10
B01D 67/00

Abstract:

Embodiments described herein relate generally to durable graphene oxide membranes for fluid filtration. For example, the graphene oxide membranes can be durable under high temperatures non-neutral pH, and/or high pressures. One aspect of the present disclosure relates to a filtration apparatus comprising: a support substrate, and a graphene oxide membrane disposed on the support substrate. The graphene oxide membrane has a first lactose rejection rate of at least 50% with a first 1 wt % lactose solution at room temperature. The graphene oxide membrane has a second lactose rejection rate of at least 50% with a second 1 wt % lactose solution at room temperature after the graphene oxide membrane is contacted with a solution that is at least 80 C. for a period of time.

Abstract:

The present disclosure provides (block co-polymer)-(metal organic framework) conjugates (BCPMOFs), such as (block co-polymer)-(metal organic nanostructure) conjugates (BCPMONs), and thermoplastic elastomers, gels, and compositions thereof. Exemplary BCPMONs include (block co-polymer)-(metal organic cage) conjugates (BCPMOCs), (block co-polymer)-(metal organic paddlewheel) conjugates, and (block co-polymer)-(metal organic square) conjugates, such as BCPMONs of Formula (A), (B), or (C). Also described herein are macromonomers for preparing the BCPMONs; thermoplastic elastomers, gels, and compositions involving the BCPMONs; methods of preparing the BCPMONs, thermoplastic elastomers, gels, and compositions; and methods of using the BCPMONs, thermoplastic elastomers, gels, and compositions.
