Two-dimensional material based filters, their method of manufacture, and their use are disclosed. In one embodiment, a membrane may include an active layer including a plurality of defects and a deposited material associated with the plurality of defects may reduce flow therethrough. Additionally, a majority of the active layer may be free from the material. In another embodiment, a membrane may include a porous substrate and an atomic layer deposited material disposed on a surface of the porous substrate. The atomic layer deposited material may be less hydrophilic than the porous substrate and an atomically thin active layer may be disposed on the atomic layer deposited material.

Mitigating leaks in membranes

Two-dimensional material based filters, their method of manufacture, and their use are disclosed. The filters may include at least one active layer disposed on a porous substrate. The at least one active layer may include intrinsic and/or intentional formed pores. In some embodiments, the flow resistance of the porous substrate may be selected to limit flow through defects and intrinsic pores in the at least one active layer.
