Mitigating leaks in membranes

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.

Formation of pores in atomically thin layers

Atomically thin layers including pores, their method of manufacture, and their use are disclosed. In some embodiments, pores may be formed in an atomically thin layer by growing the atomically thin layer on exposed portions of a substrate that includes islands comprising a material that is different than the material of the substrate. In some embodiments, pores and/or defects may be formed in an atomically thin layer by employing growth conditions that promote the formation of defects and/or pores. In certain embodiments, pores and/or defects may be etched to enlarge their size.
