Carbon Nanomaterials: Adsorption, Separations, and Transport Processes
Wednesday, November 10, 2021 - 9:40am to 10:05am
Atomically thin 2D materials offer transformative opportunities for molecular separations. Pristine monolayer
graphene and h-BN are impermeable to species larger than protons but the introduction of nanoscale defects
in the 2D material lattice allows for the creation of size-selective nanoporous atomically thin membranes.
Here, I will discuss advances in 2D material synthesis and integration/processing routes to realize i) large area
atomically thin gas barriers, ii) fully functional nanoporous atomically thin membranes for dialysis
based molecular separations, iii) novel approaches for in-situ growth of nanopores in 2D materials, iv) the
development of methods to probe sub-nanometer to nanometer defects over centimeter scale single
crystalline 2D materials, v) roll-to-roll approaches to fabricate large area atomically thin membranes and vi)
atomically thin desalination membranes. Specifically, I will focus on the role of defects and associated
engineering challenges with quality and scalability for electronics vs membrane applications. Finally, I will
discuss our efforts to move these inventions from the lab space to the commercial arena.
