Abstract: Membrane processes are finding wide uses ranging from selective separations to affinity and adsorption applications. The development of catalytic and responsive, multifunctional materials and membranes for water applications requires a high level of control of both the characteristics of the base polymeric support layer, as well as, its corresponding pore configurations. Microfiltration membranes are primarily used for the removal of bacteria and particles, but by appropriate pore functionalization with responsive polymers or integration of catalytic (enzymes or nano sized catalyst) or biomimetic (such as, porins) domains to these MF membranes we have advanced the platform both water remediation to other environmental aerosol separations. Many current treatments for the reclamation of contaminated sources are chemical-intensive, energy-intensive, and/or require post-treatment due to unwanted by-product formation. Can we use existing membranes to functionalize surface or pores and for what benefits? Can we translate water filtration membranes to air filtration? The presentation will include: (a) short overview beyond normal RO/NF/UF, (b) surface and pore functionalization approaches, (c) creation of reactive and temperature responsive domain for emerging contaminant separations, (d) extension to aerosol separation application. This research has been supported by NSF, NIH-NIEHS-SRP, Chevron, and Honeywell Corporation.
